▼ We investigate a number of techniques for increasing throughput and quality of media applications over
wireless networks. A typical media communication application such as video streaming imposes strict requirements on the delay and throughout of its packets, which unfortunately, cannot be guaranteed by the underlying
wireless network due inherently to the multi-user interference and limited bandwidth of
wireless channels. Therefore, much recent research has been focused on the joint design of network layers in order to guarantee some pre-specified Quality of Service (QoS). In this thesis, we investigate three specific settings to address the general problem of media transmission over
wireless networks. In the first setting, we propose a distributed admission control algorithm in one-hop
wireless network to decide whether or not a new flow should be injected into the network, in order to guarantee the QoS of the current flows. Next, a novel medium access control protocol and a scheduling packet algorithm are proposed for jointly optimizing the quality of video streaming applications. In the second setting, we extend the framework of the proposed admission control from a one-hop network to linear
wireless networks, consisting of multiple nodes. In the third and final setting, we present an approach for increasing the throughput of
wireless access
networks by integrating network coding and beamforming techniques.

▼ Multicast service is one of the methods used to efficiently manage bandwidth when sending multimedia content. To improve bandwidth utilisation, virtualization is often invoked because of its additional features such as bandwidth sharing and support of services that require high volumes of transactional data. Currently, network providers are concerned with the bandwidth amount for efficient use of the limited
wireless network capabilities and the provision of a better quality of service. The virtualization design of a multicast service framework should satisfy several objectives. For example, it should enable the interchange of service delivery between multiple
networks with one shareable network infrastructure. Also, it should ensure efficient use of network resources and guarantee users' demands of Quality of Service (QoS). Thus, the design of virtualization of multicast service framework is a complex research study. Due to the bandwidth-related arguments, a strong focus has been put on technical issues that facilitate virtualization in
wireless networks. A well-designed virtualized network guarantees users with the required quality service. Similarly, virtualization of multicast service is invoked to improve efficient utilisation of bandwidth in
wireless networks. As
wireless links prove to be unstable, packet loss is unavoidable when multicast service-oriented virtual artefacts are incorporated in
wireless networks. In this thesis, a virtualized multicast framework was modelled by using Generalized Assignment Problem (GAP) methodology. Mixed Integer Linear Programing (MILP) was implemented in MATLAB to solve the GAP model. This was to optimise the allocation of multicast traffic to the appropriate virtual
networks. Thus, the developed model allows users to have interchangeable services offered by multiple
networks. Furthermore, Network Simulator version 3 (NS-3) was used to evaluate the performance of the virtualized multicast framework. Three applications, namely, voice over IP (VoIP), video streaming, and file download have been used to evaluate the performance of a multicast service virtualization framework in Worldwide Interoperability for Microwave Access (WiMAX)
networks using NS-3. The performance evaluation was based on whether MILP is used or not used. The results of experimentation have revealed that there is good performance of virtual
networks when multicast traffic is sent over one single virtual network instead of sending it over multiple virtual
networks. Similarly, the results show that the bandwidth is efficiently used because the multicast traffic is not delivered through multiple virtual
networks. Overall, the concepts, the investigations and the model presented in this thesis can enable mobile network providers to achieve efficient use of bandwidth and provide the necessary means to support services for QoS differentiations and guarantees. Also, the multicast service virtualization framework provides an excellent tool that can enable network providers to interchange services. The developed…

▼ As a sensor network grows large, it may become increasingly complex in topology due to its close ties to the surrounding environment. Previous work has shown that proper geometric processing of the network (e.g., boundary detection and localization) can provide very helpful information for applications to optimize their performance. To that end, numerous algorithms have been developed, providing a variety of inspiring solutions, yet exhibiting an ad hoc style in principle and implementation. In this thesis we show that the crux of solving many of the problems caused by complex topology is to identify the concave nodes, nodes that are located at concave network corners, where the boundary has an inner angle greater than π. The knowledge of such nodes makes several important tasks, namely geometric embedding, full localization, convex segmentation, and boundary detection, relatively easier or perform significantly better, as confirmed by simulations. These findings suggest that concave nodes can serve as a basic supporting structure for general geometric processing tasks and geometry-related applications in sensor networks.

▼ Wireless sensor
networks are relatively simple, scalable
networks with many applications in the research field. They can provide benefits that a typical
wireless network does not, such as ad-hoc distribution, lower costs, and higher flexibility. In a scenario where time is of the essence and dedicated base stations cannot be established, such as a storm or a volcanic eruption, mobile sinks must be used to gather data. We aim to introduce a fast cluster-based mechanism by which nodes can securely connect to one another based on trust and network clustering and begin transmitting data to a collection device while it is available. We also examine two possible attacks on a trust-based network, and present a heuristic solution for minimizing the negative effects of such an attack in an energy-efficient way. Through simulation, we show that this scheme performs better than others in terms of energy efficiency and network lifespan.

▼ Mobile video is a key driver of lifestyle in the networked age. Reconciling demanding video applications with scarce
wireless spectrum, however, is no easy task for network researchers and operators. Traditional mobile resource management techniques may interact poorly with client-driven control of video applications. In this thesis, I propose solutions that rethink the interactions between the client¿s decisions and the network operator¿s optimizations. Through mathematical models and real-world experiments, I am to achieve fair provisioning of user quality of experience (QoE) and efficient utilization of
wireless resources.
A popular method for clients to improve video QoE under changing
wireless conditions is by changing the video bitrate to match available bandwidth (DASH). When multiple DASH clients independently compete for resources on a shared
wireless cellular link, problems arise in fairness, stability, and resource utilization. To overcome these problems, I propose a cellular resource management framework for adaptive video flows, AVIS, and validate our design on a 4G testbed.
Cellular multicast is another technique to improve
wireless resource efficiency. However, multicast aims to deliver content at the same rate to all users, whereas different
wireless users may have different physical-layer rates depending on their signal strength. My work on LTE multicast (eMBMS) explores how to optimally partition users and allocate resources to alleviate this conflict.
Finally, the vast growth of video traffic is clashing with usage-based pricing of cellular data plans imposed by network operators. Is there a way for users to stay within their monthly data quotas without suffering a noticeable degradation in video quality? QAVA is an online video adaptation system that manages this tradeoff by leveraging compressibility of different types of videos and by predicting consumer usage behavior throughout the billing cycle. I demonstrate QAVA¿s efficacy using trace-driven simulations and an Android prototype.

▼ The recent years have seen an enormous advance in wireless communication technology and co-existence of various types of wireless networks, which requires effective inter-networking among the heterogeneous wireless networks in order to support user roaming over the networks while maintaining the connectivity. One of main challenges to achieve the connectivity over heterogeneous wireless networks is potential intermittent connections caused by user roaming. The issue is how to maintain the connection as the user roams and how to ensure service quality in the presence of a long disconnection period.
In this dissertation, we apply the delay tolerant network (DTN) framework to heterogeneous terrestrial wireless networks, and propose a system architecture to achieve the connectivity in the presence of excessive long delays and intermittent paths. We study several possible approaches, discuss the applicability of each of the approaches and propose the super node architecture. To demonstrate the effectiveness of the proposed super node architecture, we give a simulation study that compares the system performance under the super node architecture and under the epidemic based architecture.
Within the proposed architecture that employs the idea of super nodes, we further study how to effectively route a message over access networks. We present a new routing technique for mobile ad-hoc networks (MANETs) based on the DTN system architecture. We introduce the concept of virtual network topology and redefine the dominating-set based routing for the challenged network environment under consideration. In addition, we propose a time based methodology to predict the probability of future contacts between node pairs to construct the virtual network topology. We present a simulation study that demonstrates the effectiveness of the proposed routing approach as compared with the epidemic routing, and that the time based technique for predicting the future contacts gives better performance compared with that using the number of previous contacts.
We further extend the dominating set routing technique through analyzing the underlying node mobility model. We shed some light on how using node mobility model can improve contact probability estimation. Based on our findings we propose a new algorithm that improves the routing performance by minimizing the selected dominating set size.
Information security challenges in the super node architecture are introduced. We further address two main security challenges: The first is how to prevent unauthorized nodes from using the network resources, and the second is how to achieve end-to-end secure message exchange over the network. Our proposed solutions are based on asymmetric key cryptography techniques. Moreover, we introduce a new idea of separating the problem of source authentication from the problem of message authorization. We propose a new technique that employs the one-way key chain to use symmetric key cryptographic techniques to address the problems under consideration.

▼ Wireless Sensor
Networks (WSNs) are an emerging technology that may one day supply real-time information to many services and Internet-based applications. The utility of WSNs relies on the ability to provide valid information, even in the presence of failures or attackers. Current research in the field has identified a large variety of attacks and countermeasures, however, few works address how WSN routing protocols can autonomously react to detected attacks. The works that do provide attack-reactive schemes generally require nodes to coordinate or exchange trust/detection reports.
This work aims to maximize data delivery in the presence of selective forwarding attacks with nodes performing detection and reaction operations independently. Via modifications to the Collection Tree Protocol's forwarding path and route update procedure, nodes autonomously evaluate their parent's forwarding reliability and duplicate data to alternative parent nodes when deemed necessary. As shown though a number of simulations, this distributed scheme yields significant data recovery with only modest overheads for attackers dropping data at medium to high rates.

▼ Wireless Mesh
Networks have proven immensely valuable in extending the reach, speed of deployment and flexibility of
networks. Routing in
wireless mesh
networks is complicated by channel interference, multi-hop pathways and the highly unpredictable nature of traffic demands, due to mobile clients and diversity of services. The goal of this dissertation is a routing strategy which provides the best possible worst-case performance while achieving a balance with the average case. We establish a baseline of a robust worst-case using oblivious routing, which uses no knowledge of traffic demand. We extend this using a series of demand models with increasing focus and time-awareness and incorporate them into our solution to enhance the average case with minimal risk to the worst-case. Finally, we accommodate multichannel and multiradio models to provide practical routings for realistic
networks.

▼ With the rapid advances in data transmission over various advanced underwater acoustic
networks, it is important to develop the efficient protocol to obtain a high data-rate with Quality of Service (QoS) guarantee requirements for acoustic
wireless communications. Because of the harsh underwater acoustic environments, such as time-varying network topology and channel conditions, limited bandwidth and constrained underwater signal propagation, we develop and implement a protocol called multi-hop adaptive RTT-driven transport layer flow and error control protocol (ARTFEC) for QoS guaranteed image transmission in underwater
wireless networks. ARTFEC is based on the congestion window size control and the Q-learning optimal timeout selection with QoS provisioning. For the congestion window size control, we propose an RTT-based data flow control policy to adapt to the varying acoustic channel environments, aiming to guarantee the reliability and high data rate of data transmission. In addition, we develop a Q-learning based optimal timeout selection algorithm to improve the channel utilization efficiency, which can increase the end-to-end throughput while decreasing the packet loss rate. We implement ARTFEC using our lab testbed, which consists of the Aqua-Net protocol stack and the acoustic OFDM modems. The testbed results obtained show that our developed ARTFEC transport layer protocol outperforms the other existing reliable data transmission schemes, in terms of end-to-end throughput and packet loss rate.

▼ As the World Wide Web becomes increasing popular, internet traffic also increases, thus increasing user perceived latency (UPL). Web page prefetching is seen as a potential solution. It involves trying to predict the user's next request and acquiring that web page while the user is busy reading their current web page. Prefetching has been an area of research interest in wired systems. Such research has shown that prefetching does lead to a reduction in UPL. However prefetching research for
wireless mesh
networks, where unlike wired systems, data traffic traverses through multiple mesh routers, which are susceptible to failure, and which can be used by numerous mesh clients to access a gateway access point is nil. This thesis applies the principles of prefetching to
wireless mesh
networks. Test results show for mesh clients, UPL is indeed decreased. Moreover this decrease in user perceived latency is also accompanied with the interesting result that there is a transformation in the distribution shape of UPLs as one goes from a
wireless mesh network system that does not engage in prefetching to one that does use prefetching.

▼ In this thesis, we propose a suite of Evolutionary Algorithms (EA)-based protocols to solve the problems of clustering and routing in Wireless Sensor Networks (WSNs). At the beginning, the problem of the Cluster Heads (CHs) selection in WSNs is formulated as a single-objective optimization problem. A centralized weighted-sum multi-objective optimization protocol is proposed to find the optimal set of CHs. The proposed protocol finds a predetermined number of CHs in such way that they form one-hop clusters. The goal of the proposed protocol is to enhance the network's energy efficiency, data delivery reliability and the protocol's scalability. The formulated problem has been solved using three evolutionary approaches: Genetic Algorithms (GA), Differential Evolution (DE) and Particle Swarm Optimization (PSO) and we assessed each of their performance. Then, a PSO-based hierarchical clustering protocol that forms two-hop clusters is proposed to investigate the effect of the number of CHs on network's energy efficiency. This protocol enhances the WSN's energy efficiency by setting an upper bound on the number of CHs and trying to minimize the number of CHs compared to that upper bound. It also maximizes the protocol's scalability by using two-hop communication between the sensor nodes and their respective CHs. Then, a centralized weighted-sum PSO-based protocol is proposed for finding the optimal inter-cluster routing tree that connects the CHs to the Base Station (BS). This protocol is appropriate when the CHs are predetermined in advance. The proposed protocol uses a particle encoding scheme and defines an objective function to find the optimal routing tree. The objective function is used to build the trade-off between the energy-efficiency and data delivery reliability of the constructed tree. Finally, a centralized multi-objective Pareto-optimization approach is adapted to find the optimal network configuration that includes both the optimal set of CHs and the optimal routing tree. A new individual encoding scheme that represents a joint solution for both the clustering and routing problems in WSNs is proposed. The proposed protocol uses a variable number of CHs, and its objective is to assign each network node to its respective CH and each CH to its respective next hop. The joint problem of clustering and routing in WSNs is formulated as a multi-objective minimization problem with a variable number of CHs, aiming at determining an energy efficient, reliable ( in terms of data delivery) and scalable clustering and routing scheme. The formulated problem has been solved using two state-of-the-art Multi-Objective Evolutionary Algorithms (MOEA), and their performance has been compared.
The proposed protocols were developed under realistic network settings. No assumptions were made about the nodes' location awareness or transmission range capabilities. The proposed protocols were tested using a realistic energy consumption model that is based on the characteristics of the Chipcon CC2420 radio transceiver data sheet.…

▼ Wireless LANs (WLANs), based on the IEEE 802.11 standard, have become the standard means for indoor wireless connectivity. At the same time, the rising number of smart mobile devices, broadband access speeds, and bandwidth hungry applications (e.g., high definition video streaming) have led to an increase not only of usage but also of demand for higher data-rates. This demand for higher rates is being met with newer IEEE 802.11 standards (e.g., 802.11n/ac) that introduce new features and also increase the different possible settings for each feature. Inherent channel variations and the possible interference conditions when operating in unlicensed spectrum necessitate adaptation of the various medium access control (MAC) and physical (PHY) layer features to ensure high performance. Selecting the values of those features to optimise a criterion such as throughput is the link adaptation problem. Link adaptation, the focus of this thesis, can play a key role in improving the performance of 802.11 WLANs. Increasing number of features and feature setting combinations with newer 802.11 standards is not only making link adaptation even more important but also more challenging. The contributions made in this thesis significantly advance the state of the art on link adaptation for 802.11 WLANs along three dimensions. First, we show that not knowing the exact cause of loss is not an impediment to effective link adaptation. Nevertheless, actions taken in response to losses are more crucial and they ought to be holistic and not solely dependent on the exact cause of loss. Second, we make significant methodological contributions for analysing the impact of multiple parameters on a given criterion, based on comprehensive experimental measurements. The application of this methodology on 802.11n measurements, examining the interaction of the protocols various parameters on performance under varying conditions, has lead to several valuable findings on how to perform efficient link adaptation in a complex WLAN scenario like 802.11n and future 802.11 standards. Adaptation should be holistic, based on the channel quality instead of the interference scenario, and independent of loss differentiation. Based on these insights, lastly and most importantly, we propose two novel holistic link adaptation schemes for legacy 802.11a/b/g and 802.11n WLANs, termed Themis and SampleLite, respectively. Both Themis and SampleLite take a hybrid approach relying on easily accessed channel quality information at the sender side to perform holistic adaptation. The hypothesis that adaptation should be holistic is validated by our results, with both Themis and SampleLite outperforming the current state of the art.

▼ Nowadays more and more sensors are being incorporated into trucks. All of these sensors are interfaced with the ECU’s using wires. This increases the cost and complexity of installing the sensors. One alternative is to make the connection wireless. Therefore, AB Volvo technologies are researching on how to develop such a system. Currently it is at the initial stages. This thesis is a small part of this research.The main aim of this thesis is to identify the best gateway position for such a wireless sensor network at the chassis of the truck. To achieve this, a test platform was built, tests were performed and empirical link analysis was done. The platform makes use of an open source operating system called Contiki OS and uses IEEE 802.15.4 compliant transceivers. All the tests were conducted on a stationary truck. Moreover, all the tests conducted had 3 variables and they are gateway position, transmission power and truck mode.From the results obtained it was found that 2 gateway positions out of the total 3 tested are equally good. Furthermore, it was found that truck modes didn’t have any impact on the wireless link.

▼ Wireless sensors and their applications have become increasingly attractive for industry, building automation and energy control, paving the way for new applications of sensor networks which go well beyond traditional sensor applications. In recent years, there has been a rapid growth in the number of wireless devices operating in close proximity to the human body. Wearable sensor nodes are growing popular not only in our normal living lifestyle, but also within healthcare and military applications, where different radio units operating in/on/off body communicate pervasively. Expectations go beyond the research visions, towards deployment in real-world applications that would empower business processes and future business cases. Although theoretical and simulation models give initial results of the antenna behaviour and the radio channel performance of wireless body area network (WBAN) devices, empirical data from different set of measurements still form an essential part of the radio propagation models. Usually, measurements are performed in laboratory facilities which are equipped with bulky and expensive RF instrumentation within calibrated and controllable environments; thus, the acquired data has the highest possible reliability. However, there are still measurement uncertainties due to cables and connections and significant variations when designs are deployed and measured in real scenarios, such as hospitals wards, commercial buildings or even the battle field. Consequently, more flexible and less expensive measurement tools are required. In this sense, wireless sensor nodes offer not only easiness to deploy or flexibility, but also adaptability to different environments. In this thesis, custom-built wireless sensor nodes are used to characterise different on-body radio channels operating in the IEEE 802.15.4 communication standard at the 2.45 GHz ISM band. Measurement results are also compared with those from the conventional technique using a Vector Network Analyser. The wireless sensor nodes not only diminished the effect of semi-rigid or flexible coaxial cables (scattering or radiation) used with the Vector Network Analyser (VNA), but also provided a more realistic response of the radio link channel. The performance of the wireless sensors is presented over each of the 16 different channels present at the 2.45 GHz band. Additionally, custom-built wireless sensors are used to characterise and model the performance of different on-body radio links in dynamic environments, such as jogging, rowing, and cycling. The use of wireless sensors proves to be less obstructive and more flexible than traditional measurements using coaxial cables, VNA or signal generators. The statistical analysis of different WBAN channels highlighted important radio propagation features which can be used as sport classifiers models and motion detection. Moreover, specific on-body radio propagation channels are further explored, with the aim to recognize physiological features such as motion pattern, breathing activity and heartbeat.…

▼ This thesis validates that packet aggregation is a viable technique to increase call capacity for Voice over Internet Protocol over
wireless mesh
networks.
Wireless mesh
networks are attractive ways to provide voice services to rural communities. Due to the ad-hoc routing nature of mesh
networks, packet loss and delay can reduce voice quality. Even on non-mesh
networks, voice quality is reduced by high overhead, associated with the transmission of multiple small packets. Packet aggregation techniques are proven to increase VoIP performance and thus can be deployed in
wireless mesh
networks. Kernel level packet aggregation was initially implemented and tested on a small mesh network of PCs running Linux, and standard baseline vs. aggregation tests were conducted with a realistic voice traffic profile in hop-to-hop mode. Modifications of the kernel were then transferred to either end of a nine node 'mesh potato' network and those tests were conducted with only the end nodes modified to perform aggregation duties. Packet aggregation increased call capacity expectedly, while quality of service was maintained in both instances, and hop-to-hop aggregation outperformed the end-to-end configuration 4:1. However, implementing hop-to-hop in a scalable fashion is prohibitive, due to the extensive kernel level debugging that must be done to achieve the call capacity increase. Therefore, end-to-end call capacity increase is an acceptable compromise for eventual scalable deployment of voice over
wireless mesh
networks.

▼ In this dissertation, we discuss various aspects of scheduling and resource allocation in multi-user
wireless systems.
This work starts from how to utilize advanced physical-layer technology to improve the system performance in a multi-user environment.
We show that by using superposition coding (SPC) and successive interference cancellation, the system performance can be greatly improved with utility-based scheduling. Several observations are made as the design guideline for such system. Scheduling algorithms are designed for a system with hierarchical modulation which is a practical implementation of SPC.
However, when the utility-based scheduling is designed, it is based on the assumption that the system is saturated, {\em i.e.}, users in the system always have data to transmit. It is pointed out in the literature that in a system with stochastic traffic, even if the arrival rate lies inside the capacity region, the system in terms of queue might not be stable with the utility-based scheduling. Motivated by this, we have studied the stability region of a general utility-based scheduling in a multi-user system with stochastic traffic. We show that the stability region is generally less than the capacity region, depends on how to interpret an intermediate control variable, and the resultant stability region may be even non-convex and exhibits undesirable properties which should be avoided.
As the utility-based scheduling cannot achieve throughput-optimal, we turn our attentions to the throughput-optimal scheduling algorithms, whose stability region is identical to the capacity region. The limiting properties of an overloaded
wireless system with throughput-optimal scheduling algorithms are studied. The results show that the queue length is unstable however the scheduling function of the queue length is stable, and the average throughput of the system converges.
Finally we study how to schedule users in a multi-user
wireless system with information-theoretic security support, which is focused on the secrecy outage probability. The problem is essentially about how to schedule users, and allocate resources to stabilize the system and minimize the secrecy outage probability. We show that there is a tradeoff between the arrival rate of the traffic and the secrecy outage probability. The relative channel condition of the eavesdropper also plays an important role to the secrecy outage probability.
In summary, we showed utility-based scheduling using SPC can improve the system performance greatly, but the utility-based scheduling has limitations: the stability region might not have desired properties. On the contrary throughput-optimal scheduling has its own drawbacks: the traffic cannot be handled properly if the system is overloaded. The further study on the secrecy outage probability gives guideline on how to design a scheduler in a system with information-theoretic security support.

▼ Interference in wireless sensor networks can have a significant impact on power consumption and throughput. In this paper, we address the problem of finding a network topology that minimizes the maximum interference experienced by any sensor in the network. In the standard interference model, each sensor interferes with every other sensor within its communication range. We approach the problem of minimizing interference by creating a linear relaxation to a similar problem with a different interference model. Using randomized rounding, this relaxation gives an O(OPT*log n) approximation to this new problem. We then show that this solution is an O(OPT2*log n) approximation to minimize the maximum interference using the standard interference model. If OPT=O(log n) (as is the case in most networks), this is an improvement over existing best known O(OPT*sqrt(n)) approximation. Additionally, we perform several experiments using simulated sensor networks where our algorithm often significantly outperforms its theoretical bounds.

▼ Due to the proliferation of data-hungry applications in smartphones and other personal mobile devices, the demand for higher data rate is increasing. This phenomenon has a huge impact on architecture of
wireless cellular
networks. Based on this fact, the architecture of
wireless cellular
networks is transforming from voice-centric and centrally-controlled to the data-centric and distributed, in order to address the massive data demand of users.One efficient approach to implement the data-centric and distributed
wireless cellular
networks is
wireless heterogeneous cellular
networks (HCN), where a multitude of radio access points with different technologies and platforms can interoperate flexibly and intelligently. However, augmenting the conventional
wireless cellular
networks with access points of different characteristics will introduce new challenges in integrating different access points to reach seamless connectivity.In order to address the broad range of challenges we face in HCNs, the need for efficient and accurate model to capture the main features of
wireless networks is paramount. The proposed model should be general but not too complicated to be difficult to gain insight. Stochastic geometry has been proven to be a powerful mathematical tool in modeling
wireless networks with irregular topologies. In this work, we incorporate principles from stochastic geometry by modeling the
wireless networks via using point processes such as Poisson point process (PPP) and Binomial point process (BPP).To be more specific, we have exploited the PPP model in modeling
wireless HCNs, while BPP model is used to model
wireless ad hoc
networks.In this thesis, we first analyze the performance of finite
wireless networks in the context of
wireless ad hoc
networks and
wireless HCNs. The significance of this part is emphasized by this fact that, in most practical scenarios the number of
wireless nodes and access points is predefined and fixed and they are deployed in a finite region. The network performance is measured from different aspects such as interference distribution, outage probability, throughput, capacity, and cell association area. In all of these scenarios, we incorporate signal-to-interference-plus-noise ratio (SINR) metrics to measure the performance of different multiple access channel schemes and association protocols.In the second part of this thesis, we focus on
wireless HCNs using the PPP model where the number of nodes and size of the deployed region can be arbitrarily large. Most of previous works focus on the case that only downlink or uplink (not both) transmissions are possible at a given channel spectrum and instant of time. In this work, we derive the network performance for decoupled association and concurrent uplink and downlink transmissions. Furthermore, different traffic patterns are studied to highlight its contribution on network performance.Finally, in the last part of the thesis, we consider the cellular-based machine type communication, where a massive number of machine type devices are…

▼ Current
wireless network architecture equips data link layer with binary transmission/idling options and gives the control of choosing other communication parameters to the physical layer. Such a network architecture is inefficient in distributed
wireless networks where user coordination can be infeasible or expensive in terms of overhead. To address this issue, an enhancement to the physical-link layer interface is proposed. At the physical layer, the enhanced interface is supported by a distributed channel coding theory, which equips each physical layer user with an ensemble of channel codes. The coding theory allows each transmitter to choose an arbitrary code to encode its message without sharing such a decision with the receiver. The receiver, on the other hand, should decode the messages of interest or report collision depending on whether or not a predetermined reliability threshold can be met. Fundamental limits of the system is characterized asymptotically using a "distributed channel capacity'' when the codeword length can be taken to infinity, and non-asymptotically using an achievable performance bound when the codeword length is finite. The focus of this dissertation is to support the enhanced interface at the data link layer. We assume that each link layer user can be equipped with multiple transmission options each corresponds to a coding option at the physical layer. Each user maintains a transmission probability vector whose entries specify the probability at which the user chooses the corresponding transmission options to transmit its packets. We propose a distributed medium access control (MAC) algorithm for a time-slotted multiple access system with/without enhanced physical-link layer interface to adapt the transmission probability vector of each user to a desired equilibrium that maximizes a chosen network utility. The MAC algorithm is applicable to a general channel model and to a wide range of utility functions. The MAC algorithm falls into the stochastic approximation framework with guaranteed convergence under mild conditions. We developed design procedures to satisfy these conditions and to ensure that the system should converge to a unique equilibrium. Simulation results are provided to demonstrate fast and adaptive convergence behavior of the MAC algorithm as well as the near optimal performance of the designed equilibrium. We then extend the distributed MAC algorithm to support hierarchical primary-secondary user structure in a random multiple access system. The hierarchical user structure is established in the following senses. First, when the number of primary users is small, channel availability is kept above a pre-determined threshold regardless of the number of secondary users that are competing for the channel. Second, when the number of primary users is large, transmission probabilities of the secondary users are automatically driven down to zero. Such a hierarchical structure is achieved without the knowledge of the numbers of primary and secondary users and without direct…

▼ In
wireless sensor
networks (WSNs), flooding is usually adopted by broadcast services to disseminate broadcast messages. However, flooding produces an excessive number of unnecessary control packets, markedly increasing overhead. This work proposes a new gossip-based scheme, in which nodes forward broadcast messages with dynamic probability to decrease the number of redundant messages and thereby improve energy efficiency. By using the novel probability table and adjustment mechanism based on neighbor conditions, nodes can obtain a suitable gossip probability. Furthermore, this work considers some special cases of uneven sensor deployment such as that contains nodes with a low degree. An efficient algorithm was also developed to maintain the stability of the proposed protocol. Hence, the proposed approach can deal with various topologies and node failure. Simulations demonstrate that applying the proposed scheme to control messages forwarding improves performance compared with that of existing gossip-based broadcasting schemes.

▼ Wireless sensor nodes are resource constrained and
have limited amount of energy. Therefore, designing protocols that
conserve energy is an important area of research. Researchers have
investigated architectures and topologies that allow energy
efficient operation of WSNs. One of the popular techniques in this
regard is clustering. A typical clustering protocol contains two
main steps: cluster head election and cluster formation. This
thesis is aimed at investigation of the cluster formation process.
We propose a Fuzzy Logic based approach that uses three descriptors
namely: energy level, distance between cluster-head and base
station, and distance between the cluster-head and the sensor’s
node. We compare our proposed model, FLCFP (Fuzzy Logic Clustering
Formation Protocol), with the most popular model, LEACH, which was
proposed previously to prolong network lifetime. FLCFP approach is
shown to prolong network lifetime. In addition, it is shown that
sensor node energy is consumed in a more uniform
fashion.

▼ Mobile Ad hoc Wireless Networks (MANETs) present a new
paradigm in which to realize a variety of communication
technologies and services. The use of stochastic event-based
simulation is a common approach to modelling MANET operations as
part of the engineering process. To improve observations many
simulations are of- ten averaged together to produce estimations of
MANET operation; however, to be statistically meaningful start-up
transients must be removed, and only ergodic data averaged. These
statistical issues of stationarity and ergodicity are often
approached in an ad-hoc manner, if at all. This thesis presents a
formal method to address these two statistical issues and applies
it to the problem of quantifying MANET operation under different
physical-layer jamming strategies. This demonstration illustrates
the complex nature of MANET operation and the need for rigorous
statistical analysis as part of the engineering
process.

▼ This project is concerned with the application of the ZigBee communication standard for implementing a temperature measurement system. Due to ZigBee's low-power and low data rate features, it is ideal for analog sensor systems. Digi's ZigBee devices called XBee are used in this project. The XBee devices meet all the ZigBee standard. The XBee device has the advantage of being programmed with API firmware (application programming interface). XBee's API provides fast and reliable communication between the remote stations and the base station. The remote station has three different modules: power supply, temperature sensor and XBee device. The power supply is designed to output 3.3V. The temperature sensor is designed so that the output stays within the XBee's maximum analog input voltage range of 0V to 1.2V. The XBee device is programmed as a router. The base station has three different modules: Arduino microcontroller, LCD display and XBee device. The Arduino is programmed to receive the analog readings from the XBee device and convert them into temperature readings The temperature readings are displayed on the LCD display. The XBee device is programmed as a coordinator. The design successfully worked for 3 remote stations and 1 base station.

▼ Wireless sensor
networks (WSNs) are systems of resource-constrained sensor nodes (SNs), distributed throughout a sensor field. Energy limitations persist due to the
wireless nature of SNs and an interest in minimizing the cost and physical footprint of SNs. Due to the resource-constrained nature of SNs, much WSN research has focused on energy-efficient communication algorithms. Communication algorithms are necessary for energy-efficient data transmission between SNs and the transmission of data collected by SNs to a base station. A popular algorithm known as Low-Energy Adaptive Clustering Hierarchy (LEACH) achieves more energy-efficient communication by organizing SNs into clusters for localized communication. When SNs are mobile, the energy efficiency of LEACH is degraded because of geographic dispersion of SN clusters. This thesis proposes LEACH-Centered Cluster-head (LEACH-CCH), a clustering algorithm aimed at improving WSN lifetime in cases of stationary and mobile sensor nodes. Mobile sensor network applications are explored including vehicle-to-infrastructure communication
networks.

▼ This dissertation focuses on the analysis, design, and application of inductor-capacitor (LC) oscillators for
wireless sensor
networks (WSNs).
First an analysis and design optimization approach for enhanced swing, low power CMOS LC oscillators is presented. A phasor based analysis is used for determining the amplitude and phase noise of these oscillators with MOSFET operation in cut-off, linear and saturation regions. The calculated steady state output amplitude and phase noise from this analysis are in agreement with Cadence Spectre simulations for different bias conditions. An application of this analysis to the design optimization of LC oscillators is also demonstrated.
This is followed by a power generation method based fast start-up analysis of resonator
based oscillators. A small signal two-port based approach that is design oriented is presented. The analysis has been validated with detailed circuit level simulations. Several MOSFET oscillator architectures have been analyzed and the start-up times compared using this analysis with applications to start-up time reduction of LC oscillators. A novel low voltage quadrature LC oscillator with a fast start-up is then presented. Simulations show that the proposed oscillator can obtain a phase noise of -150 dBc/Hz at 10 MHz offset for a 5 GHz center frequency and an FoM of 195 dBc/Hz. The proposed oscillator has a superior start-up performance compared to other low voltage quadrature LC oscillator architectures.
The design aspect of LC oscillators focuses on a new enhanced swing class-D VCO which operates from a supply voltage as low as 300 mV. The architectural advantages are described along with an analysis for the oscillation frequency. Prototype differential and quadrature variants of the proposed VCO have been implemented in a 65 nm RF CMOS process with a 5 GHz oscillation frequency. At a 350 mV supply, the measured phase noise performance for the quadrature VCO with a 5% tuning range is -137.1 dBc/Hz at 3 MHz offset with a power dissipation of 2.1 mW from a 0.35 V supply. The highest resulting figure-of-merit (FoM) is 198.3 dBc/Hz.
Finally, an application of LC oscillators for a crystal free radio-frequency (RF) receiver design has been explored. It is shown that a source-synchronous receiver with MSK modulation is a suitable choice for eliminating the crystal in WSN applications. Design trade-offs
have been analyzed using system level simulations.

▼ The conventional design of
wireless networks is based on a centralized architecture where a base station, or an access point, directly exchanges data with the end users, and communication is restricted to the one-to-many (broadcast) and many-to-one (multiple-access) single-hop paradigms. However, as the number of users and the data demand increase dramatically, and we move towards the future of
wireless networks, multi-hop and multi-flow paradigms are expected to play a central role by enabling a denser spatial reuse of the spectrum and the adaptation to heterogeneous network scenarios characterized by the presence of low-power nodes, relays, and user-operated infrastructure. A major challenge in multi-hop multi-flow
wireless networks is that "interference management" and "relaying" are coupled with each other. In other words,
wireless relay nodes must play a dual role: they serve as intermediate steps for multi-hop communication and as part of the mechanism that allows interference management schemes. Nonetheless, in the information theory literature, these two tasks have traditionally been addressed separately, and the fundamental principles of the "
networks of the future" are currently not well understood. In this dissertation, we take a unified approach to relaying and interference management, and seek to develop tools to study the fundamentals of multi-hop multi-flow
wireless networks. In the first part of the dissertation, we study multi-hop multi-flow
wireless networks from a high-SNR, or degrees-of-freedom (DoF) perspective. We first consider multi-hop two-unicast
networks, and characterize the DoF as a function of the network graph. Then, we consider K x K x K
wireless networks and introduce a coding scheme called Aligned Network Diagonalization (AND) that allows the relays to neutralize all the interference experienced by the destinations. This proves that K x K x K
wireless networks have K DoF and demonstrates the potential of a coupled approach to relaying and interference management. In the second part of the dissertation, we present a characterization of the Gaussian noise as the worst-case additive noise in multi-hop multi-flow
wireless networks. Besides generalizing a classical point-to-point information theory result, this provides theoretical support for the widespread adoption of Gaussian noise models and yields a tool for obtaining capacity outer bounds for Gaussian
networks by considering
networks with different noise statistics. In the final part of the dissertation, we introduce new techniques to obtain capacity outer bounds for multi-hop multi-flow
networks. First, we use the worst-case noise result to show that the capacity region of K xK xK
wireless networks with general connectivity can be outer-bounded by the capacity region of the same network under the truncated deterministic model. We then present a generalization of the classical cut-set bound for multi-hop multi-flow deterministic
networks, which, besides recovering and unifying other previously known bounds, yields new applications,…

▼ The requirement of transmission going up in a
challenging natural environment with an adaptable and trustworthy
way of intensifying data communication has triggered for
advancement of Wireless networks The data propagation through the
air medium is done in the form of electromagnetic wave and
therefore reducing the necessity of wired data communication
Wireless local area network provides the facility of node mobility
communication with each other devices in a short range By way of
uniting the wireless communication and mobile devices the vision of
being linked with anyone anywhere in the world is possible in
reality A major downside of the usage in wireless networks depends
on the centralized administration of fixed wireless infrastructures
In a disaster or emergency circumstances the fixed infrastructure
networks become unserviceable At such times an alternative
communication facility is desperately required or a backup mode of
transmission in emergency circumstances can be constructed with
Wireless Ad Hoc Networks Usually most of the routing algorithm uses
single cost routing where each path is characterized by a scalar
with the sum of costs that characterize each of its constituent
links The link costs can be a utility of several network parameters
but they are still scalar Whereas in multi cost routing each link
is consigned with parameters of cost vector and path cost vector
constructed on cost vectors of links to the
network

▼ The focus of this research is to develop an event detection system for groundwater flooding. The groundwater monitoring infrastructure is based on a
Wireless Sensor Network, which can often lead to corrupted data values. The event detection system seeks to develop an algorithm to identify these corrupted data values and flag them as a false event to the user. It aims to maintain a high accuracy of true events, while keeping the occurrence of a false event to a minimum. The algorithm is based on threshold classification technique to identify the event and a statistical modified Z Score calculation to determine if the event is true or false. I ran the algorithm with an historic flood event and measured the accuracy of the results with a ROC curve. Results showed a 95% accuracy level but it also identified 8 out of 160 true events as false, which leads me to recommend a further analysis into the threshold that defined the algorithm. The technique would also need to be tested on larger dataset to validate this accuracy.

▼ In this dissertation, we develop and analyze effective energy management policies for
wireless sensor
networks in emerging applications. Existing methods in this area have primarily focused on energy conservation through the use of various communication techniques. However, in most applications of
wireless sensor
networks, savings in energy come at the expense of several performance parameters. Therefore it is necessary to manage energy consumption while being conscious of its effects on performance. In most cases, such energy-performance issues are specific to the nature of the application. Our research has been motivated by new techniques and applications where efficient energy-performance trade-off decisions are required.
We primarily study the following trade-off cases: energy and node replacement costs (Case I), energy and delay (Case II), and energy and availability (Case III). We consider these trade-off situations separately in three distinct problem scenarios. In the first problem (Case I), we consider minimizing energy and node replacement costs in underwater
wireless sensor
networks for seismic monitoring application. In this case, we introduce mixed-integer programming (MIP) formulations based on a combined routing and node replacement policy approach and develop effective policies for large problem instances where our MIP models are intractable. In the second problem (Case II), we develop a Markov decision process (MDP) model to manage energy-delay trade-off in network coding which is a new energy-saving technique for
wireless networks. Here we derive properties of the optimal policy and develop in- sights into other simple policies that are later shown to be efficient in particular situations. In the third problem (Case III), we consider an autonomous energy harvesting sensor network where nodes are turned off from time to time to operate in an “energy-neutral” manner. In this case, we use stochastic fluid-flow analysis to evaluate and analyze the availability of the sensor nodes under effective energy management policies.
In each of the above problem cases, we develop analytical formulations, and derive and/or analyze policies that effectively manage the considered energy-performance trade-off. Overall, our analyses and solution methods make new contributions to both operations research and communication networking literature.
