▼ A wireless sensor network (WSN) provides a platform for embedded sensing and ubiquitous computing. For ad hoc WSNs, multi-hop routing has been adopted in order to save communication power consumption. By acknowledging the lossy characteristics of radio channels on low-power WSNs, the Opportunistic Routing (OR) protocol provides an efficient method for exploiting the spatial and temporal characteristics of these wireless networks by considering multiple forwarding relays for each transmission. The main contribution of this thesis is to provide analysis and modelling for variants of the OR protocol for WSNs. Firstly, based on the basic concepts that underpin OR, we propose a new variant of OR that can be used in WSNs. It is known that communication in WSN is the most power consuming operation; hence, we propose a variant of OR that specifically reduces the total number of transmissions required during the coordination step used in OR. We investigate the effectiveness of this approach and compare it with OR that adopts existing and common candidate coordination schemes. In addition, we also propose a retransmission scheme based on provisional reliability constraints for local loss recovery that can be used in this new variant of OR. Secondly, we propose a comprehensive new analytical framework that is based on Markov Chain and Queueing theories that takes into account the key component strategies of OR (prioritization, selection and coordination) as well as the communication components of WSN. The proposed framework can be used to model the end-to-end reliability and delay performances of WSNs using OR. Thirdly, taking into account the potential deficiencies of OR due to its static coordination scheme, we introduce a variant of OR that is aware of the online quality of its selected forwarding relays that we have named as the Adaptive Coordination Opportunistic Routing (ACOR) protocol. We propose a new local metric to be known as the Opportunistic Quality Score for ACOR to improve the performance of WSNs and, in particular, to support Quality of Service delivery of messages in these networks. In addition, we provide an analytical framework for ACOR that incorporates the adaptive coordination scheme that has been developed.

▼ Delay Tolerant Networks (DTNs) are characterized by the lack of continuous end-to-end connections because of node mobility, constrained power sources, and limited data storage space of some or all of its nodes. Applications of DTNs include vehicular networks and sensor networks in suburban and rural areas. The intermittent connection in DTNs creates a new and challenging environment that has not been tackled before in wireless and wired networks. Traditional routing protocols fail to deliver data packets because they assume the existence of continuous end-to-end connections. To overcome the frequent disconnections, a DTN node is required to store data packets for long periods of time until it becomes in the communication range of other nodes. In addition, to increase the delivery probability, a DTN node spreads multiple copies of the same packet on the network so that one of the copies reaches the destination. Given the limited storage and energy resources of DTN nodes, there is a trade off between maximizing delivery and minimizing storage and energy consumption. DTN routing protocols can be classified as either blind routing, in which no information is provided to select the next node in the path, or guided routing, in which some network information is used to guide data packets to their destinations. In addition they differ in the amount of overhead they impose on the network and its nodes. The objective of DTN routing protocols is to deliver as many packets as possible. Acquiring network information helps in maximizing packet delivery probability and minimizing the network overhead resulting from replicating many packet copies. Network information could be node contact times and durations, node buffer capacities, packet lifetimes, and many others. The more information acquired, the higher performance could be achieved. However, the cost of acquiring the network information in terms of delay and storage could be high to the degree that render the protocol impractical. In designing a DTN routing protocol, the trade-off between the benefits of acquiring information and its costs should be considered. In this thesis, we study the routing problem in DTN with limited resources. Our objective is to design and implement routing protocols that effectively handles the intermittent connection in DTNs to achieve high packet delivery ratios with lower delivery cost. Delivery cost is represented in terms of number of transmissions per delivered packet. Decreasing the delivery cost means less network overhead and less energy consumption per node. In order to achieve that objective, we first target the optimal results that could be achieved in an ideal scenario. We formulate a mathematical model for optimal routing, assuming the presence of a global observer that can collect information about all the nodes in the network. The optimal results provide us with bounds on the performance metrics, and show the room for improvement that should be worked on. However, optimal routing with a global observer is just…

▼ An Opportunistic Mobile Network (OMN) refers to the network paradigm where wireless devices communicate with each other through the opportunistically formed wireless links. Routing in OMN relies on node mobility and the store-and-forward mechanism. It is paramount to have energy efficient, robust and cost effective routing protocols in such environments. Previous research usually assumes that the connectivity in such networks is extremely sparse and that the network is purely infrastructure-less. However, real world deployments of OMNs actually exhibit di- verse connectivity, i.e., connectivity may range from sparsely connected to well connected or the network may coexist with infrastructure. Consequently, the simplified assumptions of previous solutions lead to suboptimal behaviors of routing protocols, which includes redundant transmissions, too much or insufficient data replications, poor forwarding decisions, etc. In this dissertation, in order to address the aforementioned problems, we propose a communication framework for OMNs with diverse connectivity, which consists of a series of algorithms and protocols that aim to provide energy efficient, robust and cost-aware communication services to applications. In this framework, we propose: a) algorithms that carefully schedule transmissions in an opportunistic contact involving multiple nodes; b) routing protocols that consider simultaneously mobile nodes' delivery capability and traffic load; c) mathematical tools that characterize not only Inter-Contact Times but also their correlations; d) adaptive mechanisms to realize dynamic data replication; and e) forwarding strategies that optimally trade-o_ energy consumption and delay in a cost-aware fashion when utilizing infrastructure. We evaluate the proposed routing protocols and algorithms through extensive simulations using both synthetic network models and real world mobility traces. We also conduct real world experiments on a wireless testbed to demonstrate their practicability. The evaluation results show that, with the assumption of diverse connectivity in mind, the proposed algorithms and protocols greatly improve the networking performance and efficiency. The consideration of delay correlations and a mechanism for dynamic replication are critical for a routing protocol to perform well with a wide range of network connectivity. When infrastructure is present, our proposed forwarding strategy helps improve the energy-delay trade-off when cost is a constraint.

▼ In wireless communication, many technologies, such as Wi-Fi, BlueTooth and ZigBee, operate in the same ISM band. With the exponential growth of wireless devices, the ISM band becomes more and more crowded. These wireless devices compete with each other to access spectrum resources, generating cross-technology interference (CTI). Since cross-technology interference may destroy wireless communication, the field is facing an urgent and challenging need to investigate the packet reception quality of wireless links under CTI. In this dissertation, we propose an in-depth systematic study from empirical measurement, theoretical analysis, modeling, to design and implementation of protocols that exploit packet reception patterns of wireless links under cross-technology interference. Based on extensive measurements, we exploit link correlation phenomenon that packet receptions from a transmitter to multiple receivers are correlated. We then propose link correlation model which contradicts the widely made link independent assumption. The proposed model has a broad impact on network designs that utilize concurrent wireless links, which include (i) traditional network protocols such as broadcast, and (ii) diversity-based protocols such as network coding and opportunistic routing. In the study of the impact of link correlation model on traditional network protocols, we present the design and implementation of CorLayer, a general supporting layer for energy efficient reliable broadcast that carefully blacklists certain poorly correlated wireless links. We integrate CorLayer transparently with sixteen state-of-the-art broadcast protocols specified in thirteen publications on three physical testbeds running TelosB, MICAz, and GreenOrbs nodes, respectively. The experimental results show that CorLayer remarkably improves energy efficiency across a wide spectrum of broadcast protocols and that the total number of packet transmissions can be reduced consistently by 47% on average. In the study of the impact of link correlation model on diversity-based protocols, we propose link correlation aware network coding and link correlation aware opportunistic routing. In link correlation aware network coding, we introduce Correlated Coding which seeks to optimize the transmission efficiency by maximizing necessary coding opportunities. In link correlation aware opportunistic routing, we propose a novel candidate forwarder selection algorithm to help opportunistic routing fully exploit the diversity benefit of the wireless broadcast medium. Testbed evaluation and extensive simulation show that the traditional network coding and opportunistic routing protocols’ transmission efficiency is significantly improved with our link correlation model.

▼ With the increasing popularity of portable digital devices (e.g., smartphones, laptops, and tablets), mobile opportunistic networks (MONs) [40, 90] consisting of portable devices have attracted much attention recently. MONs are also known as pocket switched networks (PSNs) [52]. MONs can be regarded as a special form of mobile ad hoc networks (MANETs) [7] or delay tolerant networks (DTNs) [35, 56]. In such networks, mobile nodes (devices) move continuously and meet opportunistically. Two mobile nodes can communicate with each other only when they are within the communication range of each other in a peer-to-peer (P2P) manner (i.e., without the need of infrastructures). Therefore, such a network structure can potentially provide file sharing or packet routing services among portable devices without the support of network infrastructures. On the other hand, mobile opportunistic networks often experience frequent network partition, and no end-to-end contemporaneous path can be ensured in the network. These distinctive properties make traditional file sharing or packet routing algorithms in Internet or mobile networks a formidable challenge in MONs. In summary, it is essential and important to achieve efficient file sharing and packet routing algorithms in MONs, which are the key for providing practical and novel services and applications over such networks. In this Dissertation, we develop several methods to resolve the aforementioned challenges. Firstly, we propose two methods to enhance file sharing efficiency in MONs by creating replicas and by leveraging social network properties, respectively. In the first method, we investigate how to create file replicas to optimize file availability for file sharing in MONs. We introduce a new concept of resource for file replication, which considers both node storage and meeting frequency with other nodes. We theoretically study the influence of resource allocation on the average file access delay and derive a resource allocation rule to minimize the average file access delay. We also propose a distributed file replication protocol to realize the deduced optimal file replication rule. In the second method, we leverage social network properties to improve the file searching efficiency in MONs. This method groups common-interest nodes that frequently meet with each other into a community. It takes advantage of node mobility by designating stable nodes, which have the most frequent contact with community members, as community coordinators for intra-community file request forwarding, and highly-mobile nodes that visit other communities frequently as community ambassadors for inter-community file request forwarding. Based on such a community structure, an interest-oriented file searching scheme is proposed to first search local community and then search the community that is most likely to contain the requested file, leading to highly efficient file sharing in MONs. Secondly, we propose two methods to realize efficient packet routing among mobile nodes and among different… Advisors/Committee Members: Dr. Haiying Shen, Dr. Richard R.

▼ Data transmission has become a need in various fields, like in social networks with the diverse interaction applications, or in the scientific and engineering areas where for example the use of sensors to capture data is growing, or in emergency situations where there is the imperative need to have a communication system to coordinate rescue operations. Wireless networks have been able to solve these issues to a great extent, but what can we do when a fixed supporting infrastructure is not available or becomes inoperative because of saturation? Opportunistic wireless networks are an alternative to consider in these situations, since their operation does not depend on the existence of a telecommunications infrastructure but they provide connectivity through the organized cooperation of users. This research thesis focuses on these types of networks and is aimed at improving the dissemination of information in opportunistic networks analyzing the main causes that influence the performance of data transmission. Opportunistic networks do not depend on a fixed topology but depend on the number and mobility of users, the type and quantity of information generated and sent, as well as the physical characteristics of the mobile devices that users have to transmit the data. The combination of these elements impacts on the duration of the contact time between mobile users, directly affecting the information delivery probability. This thesis starts by presenting a thorough "state of the art" study where we present the most important contributions related to this area and the solutions offered for the evaluation of the opportunistic networks, such as simulation models, routing protocols, simulation tools, among others. After offering this broad background, we evaluate the consumption of the resources of the mobile devices that affect the performance of the the applications of opportunistic networks, both from the energetic and the memory point of view. Next, we analyze the performance of opportunistic networks considering either pedestrian and vehicular environments. The studied approaches include the use of additional fixed nodes and different data transmission technologies, to improve the duration of the contact between mobile devices. Finally, we propose a diffusion scheme to improve the performance of data transmission based on extending the duration of the contact time and the likelihood that users will collaborate in this process. This approach is complemented by the efficient management of the resources of the mobile devices.; La transmisión de datos se ha convertido en una necesidad en diversos ámbitos, como en las redes sociales con sus diversas aplicaciones, o en las áreas científicas y de ingeniería donde, por ejemplo, el uso de sensores para capturar datos está creciendo, o en situaciones de emergencia donde impera la necesidad de tener un sistema de comunicación para coordinar las operaciones de rescate.

▼ This thesis aims to examine the efficiency of opportunistic multicast routing in Wireless Mesh Network (WMN). Specifically, an opportunistic multicast routing protocol has been developed in this work in order to gain better performance in WMNs compared to traditional multicast routing protocols. The number of transmissions in the network to deliver a packet from a source to group of destinations has been taken as measure for the performance of the protocol. Less number of transmissions in the network to deliver a packet to group of destinations is an indicator for a better performance.The work has been divided into two parts. In the first part, a proposal of the first version of opportunistic multicast routing protocol (OMRPv1) will be explained. By calculating the expected number of transmissions in the network, the efficiency of the protocol will be examined. OMRPv1 will be compared against a traditional protocol, non-opportunistic protocol, to confirm its better performance in the network. Then, a second version of our protocol will be introduced, OMRPv2, as a solution for some problems encountered in the first version. The comparison between OMRPv1 and OMRPv2 will show the better performance achieved with the newer version.In the second part, QualNet simulator will be used to simulate the protocol OMRPv2. In this part, not only the number of transmissions in the network will be considered, but also other metrics like end to end delay and delivery rate will be taken into account. The overhead of the protocol will be examined as well. Observation of the results from the simulation will lead to the third version of the protocol (OMRPv3). OMRPv3 will be simulated as well to show the improvement in the performance over the previous version OMRPv2.Finally, OMRPv3 will be compared to the best opportunistic multicast routing protocol in the literature, Beacon-less Geographic Routing for Multicast Applications (BRUMA). For that reason, BRUMA will be simulated in QualNet as well. For fair comparison, few modifications will be added to BRUMA. Then, the two protocols will be compared to each other using many metrics. Delivery rate, end to end delay, and number of transmissions in the network to serve the multicast groups are some of the metrics that will be used to compare the two protocols. Results show that our protocol, OMRPv3, outperforms BRUMA in many of these metrics. Advisors/Committee Members: Chou, Chun Tung, Computer Science & Engineering, Faculty of Engineering, UNSW.

L’Internet a complètement révolutionné la façon dont nous communiquons. En parallèle, la croissance importante des réseaux mobiles s'est accompagnée d'une explosion du nombre d’usagers et d'une augmentation exponentielle de la demande. Cependant, l’Internet n'est pas encore, voire n'est pas toujours, universellement accessible. Par exemple, c'est le cas en ce qui concerne l’accès dans les économies émergentes ou dans les régions éloignées, les obstacles physiques empêchant le déploiement de réseaux mobiles et les désastres naturels. C'est dans ce contexte que les réseaux tolérants au délai ont été introduits pour faire face aux environnements caractérisés par des interruptions et des délais de transmission élevés. Ces réseaux, manquent souvent de routes pré-déterminées ou même de toute infrastructure pour permettre une communication de bout-en-bout. Dans ce contexte, tous les nœuds de ces réseaux peuvent interagir en utilisant leurs contacts comme une opportunité de communication. Le paradigme stockage/transport permet à ces nœuds d’exploiter des chemins spatio-temporels créés par ces possibilités de contact afin de livrer des messages au fil du temps. Dans ce travail, nous soulevons ici une question générique : pouvons-nous concevoir une infrastructure mobile et opportuniste qui pourrait aider à transmettre ces messages ? Afin de fournir une telle infrastructure, nous étudions l’application des marches aléatoires temporelles (TRWs) dans réseaux opportunistes. Nous explorons l’application et l’impact de la TRW pour fournir une infrastructure minimale et non-invasive à partir de deux points de vue : le stockage des données et leur transmission.

The Internet has entirely reshaped the way we communicate and interact with one another. The rapid development of the wireless infrastructure by network providers has being accompanied by an exponential growth in the number of mobile users. However, global Internet access and connectivity still face several challenges: scarce or poor quality connectivity in developing countries or places with limited accessibility, physical obstacles limiting the deployment of wireless networks and natural or man-made disasters. Delay tolerant networks (DTNs) were introduced to deal with environments where interruptions or disruptions of service were expected. Such networks usually lack of end-to-end paths or any infrastructure to help communications. In these networks, mobile nodes may interact using their contacts as a communication opportunity. The store-carry-forward paradigm allows nodes to exploit spatio-temporal paths created by contact opportunities in order to deliver messages over time. Instead we raise the question: can we design a mobile and opportunistic infrastructure that could help deliver messages? In the quest to provide such infrastructure, we study the application of temporal random walks (TRW) over the opportunistic networks. We explore the application and impact of TRW as a minimal and non invasive infrastructure from two points of view: data forwarding and data…

▼ [ES] La disponibilidad y el rendimiento de las actuales tecnologías inalámbricas como WiFi o 4G, pueden tener serios problemas de congestión y propagación, especialmente en espacios muy concurridos, o bien ser inaccesibles en sitios remotos o con baja densidad de personas. La utilización de las Redes Oportunistas en este tipo de escenarios puede ser la solución a estos problemas. Estas redes se basan en la oportunidad de intercambiar mensajes utilizando algún tipo de tecnología de comunicación directa entre dispositivos móviles como son Bluetooth o WiFi. El rendimiento de las Redes Oportunistas depende principalmente de la movilidad de los nodos y los protocolos de enrutamiento utilizados, siendo estos últimos los encargados de decidir como son intercambiados los mensajes cuando un contacto ocurre, intentando encontrar la mejor ruta para que un mensaje alcance su destino. Por otra parte, la eficiencia de la difusión en estas redes está ligada especialmente a la movilidad de los usuarios y al comportamiento humano. Entonces, para el análisis y la evaluación del rendimiento de las Redes Oportunistas es necesario considerar tanto los aspectos técnicos relacionados con los protocolos de encaminamiento, como los aspectos de la movilidad humana. Esta tesis doctoral se centra principalmente en evaluar la diseminación de la información usando redes oportunistas en escenarios urbanos, en los que existen diferentes densidades y tasas de renovación de personas, es decir, con usuarios que puedan entrar y salir del escenario evaluado. Dado que la existencia de este tipo de trazas reales es muy limitada, en esta tesis se plantea la generación de este tipo de trazas de forma sintética. Para ello, mediante el uso de un simulador de movilidad peatonal, se han generado trazas realistas de movilidad con diferentes grados de densidad y tasas de renovación de usuarios con el objeto de evaluar diferentes aspectos de la difusión de mensajes en las Redes Oportunistas. El análisis de las características temporales y espaciales de estas trazas generadas refleja el realismo de los escenarios que se han considerado. Además, los experimentos relativos a la difusión de mensajes realizados con estas trazas, confirman que la tasa de renovación tiene un gran impacto en el rendimiento de los protocolos, lo que es particularmente evidente cuando el tamaño de los mensajes es mayor. Por otra parte, también se ha realizado el estudio, utilizando en este caso trazas reales, de la difusión de información a través de las Redes Oportunistas Vehiculares. Ya que de la misma manera la movilidad de estos vehículos está ligada al comportamiento humano, nos hemos centrado en la diseminación de la información en determinadas horas del día dependiendo del número de vehículos en circulación, debido a que este aspecto tiene un gran impacto en el reenvío de datos. Los resultados de estos experimentos confirman que los dos principales factores que afectan a la difusión de información son el grado de movilidad y el tamaño de mensaje.

▼ The increasing interest in wireless sensor networks can be promptly understood simply by thinking about what they essentially are: a large number of small sensing self-powered nodes which gather information or detect special events and commu- nicate in a wireless fashion, with the end goal of handing their processed data to a base station. Sensing, processing and communication are three key elements whose combination in one tiny device gives rise to a vast number of applications [5, 46]. Sensor networks provide endless opportunities, but at the same time pose formi- dable challenges, such as the fact that energy is a scarce and usually non-renewable resource. The minimization of energy expenditure in the sensing nodes is a natural direction for wireless sensor network research. Reducing the computational load and minimizing radio power consumption are necessary steps dictated by common sense; on the radio side, the knowledge of the properties of the wireless medium can help minimize packet loss. Wireless analytical models are useful, but the oversimplifica- tions introduced by many of them can lead to wrong considerations and conclusions. For this reason, it is essential to analyze the wireless medium with real hardware. Sensor network design should be performed by considering the interactions between the physical layer and the upper layers: physical layer phenomena should be taken into account in the development of MAC and routing schemes. In the present work, we consider the impact of multipath fading on sensor networks. Chapter 2 focuses on the analysis of the properties of multipath fading, and the verification of the most common models through software simulations and tests based on hardware implementations. In Chapter 3, we use the properties of multipath fading to pro- pose a novel, lightweight protocol for the acquisition of data from the nodes in a wireless sensor network based on the exploitation of mobility and the concept of opportunistic transmissions. Our protocol aims at the avoidance of packet loss by the nodes and the minimization of their energy consumption. While Chapter 3 revolves around the mitigation of the eå¨ects of multipath fading, chapter 4 describes a novel idea for its constructive exploitation. We show how the footprint of multipath fading on the received signal strength can be used for purposes of motion detection. The present work is completed by an appendix where extra details specific to our hardware implementations are provided to the interested reader. In the rest of the present chapter, we provide an overview of the research efforts in the field of wireless sensor networks. We start by listing some interesting applications and research projects currently underway. We then indicate the main peculiarities of sensor networks to give a feeling and basic understanding of what makes them unique and to justify the enormous interest in the field that is being displayed by the community. Finally, we present the most interesting and commonly used hardware platforms that enable wireless… Advisors/Committee Members: Martin Haenggi, Committee Chair, J.

▼ Opportunistic spectrum access (OSA) promises to significantly improve the utilization of the RF spectrum. Under OSA, an unlicensed secondary user (SU) is allowed to detect and access under-utilized portions of the licensed spectrum, provided that such operation does not interfere with the communication of licensed primary users (PUs). Cognitive radio (CR) is a key enabling technology of OSA. In this dissertation, we propose several radio resource management and routing mechanisms that optimize the discovery and utilization of spectrum opportunities in a cognitive radio network (CRN). First, we propose a sequential channel sensing and probing mechanism that enables a resource-constrained SU to efficiently identify the optimal transmission opportunity from a pool of potentially usable channels. This mechanism maximizes the SUs expected throughput by accounting for the tradeoff between the reward and overhead of scanning additional channels. The optimal channel sensing and probing process is modeled as a maximum-rate-of-return problem in optimal stopping theory. Operational parameters, such as sensing and probing times, are optimized by exploiting the problem's special structure. Second, we study the problem of coordinated spectrum access in CRNs to maximize the CRNs throughput. By exploiting the geographic relationship between an SU and its surrounding PUs, we propose the novel concept of microscopic spectrum opportunity, in which active SUs and PUs are allowed to operate in the same region, subject to power constraints. Under this framework, we formulate the coordinated channel access problem as a joint power/rate control and channel assignment optimization problem. Centralized and distributed approximate algorithms are proposed to solve this problem efficiently. Compared with its macroscopic counterpart, we show that the microscopic-spectrum-opportunity framework offers significant throughput gains. Finally, at the network layer, we study the problem of truthful least-priced-path (LPP) routing for profit-driven CRNs. We design a route selection and pricing mechanism that guarantees truthful spectrum cost reporting from profit-driven SUs and that finds the cheapest route for end users. The problem is investigated with and without capacity constraints at individual nodes. In both cases, polynomial-time algorithms are developed to solve the LPP problem. Extensive simulations are conducted to verify the validity of the proposed mechanisms.

▼ In a battery-less sensor network, all the operation of sensor nodes are strictly constrained by and synchronized with the fluctuations of harvested energy, causing nodes to be disruptive from network and hence unstable network connectivity. Such wireless sensor network is named as energy-synchronized sensor networks. The unpredictable network disruptions and challenging communication environments make the traditional communication protocols inefficient and require a new paradigm-shift in design. In this thesis, I propose a set of algorithms on collaborative data communication and storage for energy-synchronized sensor networks. The solutions are based on erasure codes and probabilistic network codings. The proposed set of algorithms significantly improve the data communication throughput and persistency, and they are inherently amenable to probabilistic nature of transmission in wireless networks. The technical contributions explore collaborative communication with both no coding and network coding methods. First, I propose a collaborative data delivery protocol to exploit the optimal performance of multiple energy-synchronized paths without network coding, i.e. a new max-flow min-variance algorithm. In consort with this data delivery protocol, a localized TDMA MAC protocol is designed to synchronize nodes' duty-cycles and mitigate media access contentions. However, the energy supply can change dynamically over time, making determined duty cycles synchronization difficult in practice. A probabilistic approach is investigated. Therefore, I present Opportunistic Network Erasure Coding protocol (ONEC), to collaboratively collect data. ONEC derives the probability distribution of coding degree in each node and enable opportunistic in-network recoding, and guarantee the recovery of original sensor data can be achieved with high probability upon receiving any sufficient amount of encoded packets. Next, OnCode, an opportunistic in-network data coding and delivery protocol is proposed to further improve data communication under the constraints of energy synchronization. It is resilient to packet loss and network disruptions, and does not require explicit end-to-end feedback message. Moreover, I present a network Erasure Coding with randomized Power Control (ECPC) mechanism for collaborative data storage in disruptive sensor networks. ECPC only requires each node to perform a single broadcast at each of its several randomly selected power levels. Thus it incurs very low communication overhead. Finally, I propose an integrated algorithm and middleware (Ravine Stream) to improve data delivery throughput as well as data persistency in energy-synchronized sensor network.

▼ Opportunistic communication leverages communication opportunities arising by chance to provide significant performance benefit and even enable communication where it would be impossible otherwise. The goal of this dissertation is to optimize opportunistic communication to achieve good performance in wireless networks. A key challenge in optimizing opportunistic communication arises from dynamic and incidental nature of communication. Complicated wireless interference patterns, high mobility, and frequent fluctuations in wireless medium make the optimization even harder. This dissertation proposes a series of optimization frameworks that systematically optimizes opportunistic communication to achieve good performance in wireless mesh networks and vehicular networks. We make the following three major contributions: First, we develop novel algorithms, techniques, and protocols that optimize opportunistic communication of wireless mesh network to achieve good, predictable user performance. Our framework systematically optimizes end-to-end performance (e.g., total throughput). It yields significant improvement over existing routing schemes. We also show that it is robust against inaccuracy introduced by dynamic network conditions. Second, we propose a novel overlay framework to exploit inter-flow network coding in opportunistic routing. In this framework, an overlay network performs inter-flow coding to effectively reduce traffic imposed on the underlay network, and an underlay network uses optimized opportunistic routing to provide efficient and reliable overlay links. We show that inter-flow coding together with opportunistic routing and rate-limiting brings significant performance benefit. Finally, we develop a novel optimization framework in vehicular networks to effectively leverage opportunistic contacts between vehicles and access points (APs). We develop a new mobility prediction algorithm and an optimization algorithm to determine an efficient replication scheme that exploit the synergy among Internet connectivity, local wireless connectivity, mesh network connectivity, and vehicular relay connectivity. Based on our framework, we develop a practical system that enables high-bandwidth content distribution and demonstrate the effectiveness of our approach using simulation, emulation, and testbed experiments.

▼ Modern society is surrounded by an ample spectrum of personal mobile devices with short-range wireless communication support. This ubiquity creates an immense potential of new concepts for people-centric ad hoc networks that can be applied to every personal and social dimension of life. The last decade introduced the concept of Opportunistic Networks (OppNets) that facilitates delay-tolerant information sharing between mobile users anytime, anywhere, and every which way possible. OppNets constitute an appealing solution to provide connectivity in those situations where communication is desired, but situated network architectures fail to provide it effectively. Despite the mobile revolution that the world is relishing today, the support of modern wireless technology in smart mobile devices is quite limited to fulfill OppNet services. While having promising potentials, the current wireless standards (e.g. Wi-Fi, Bluetooth) have restricted or hidden support for ad hoc communications in mobile operating systems. So far, such limitations have stimulated little research efforts to devise an alternative solution for the realization of OppNets. Besides, these standards are designed to achieve ad hoc communications under stable connectivity, therefore cannot cope with the highly-dynamic characteristics of OppNets. Intrinsically, OppNets rely on mobility of users to extend the dimension of communications over large distances. By and large, the mobility assistance greatly needed by OppNets requires innovative design considerations for the networks of smart mobile devices. This thesis focuses on the design, implementation, and analysis of a novel OppNet architecture intended for smart mobile platforms. Named Cocoon (Community-oriented Context-aware Opportunistic Networking), this architecture assists the practical development of a wide range of OppNet applications offered for general public use. Cocoon integrates versatile and lightweight opportunistic communication methods with a new collection of applications which are freely accessible by any group of mobile users. The presented applications span a rich collection of applications, such as short message services in challenged environments, safety monitoring in vehicular environments, and data dissemination in several demanding scenarios. In order to carry out these applications, Cocoon introduces a versatile and lightweight connectivity scheme, called opportunistic beacons, that expedites rapid and energy-efficient information sharing between smart mobile devices without requiring connections and sophisticated configurations. The design of opportunistic beacons is generic, so that it is readily integrable on top of the commonly-used wireless interfaces such as Wi-Fi and Bluetooth. The Cocoon architecture employs opportunistic beacons in the design and management of networking and application services. As a networking service, Opportunistic Beacon Networking (OBN) is introduced. Within OBN, a forwarding protocol is proposed and validated with extensive real-world experiments.… Advisors/Committee Members: Havinga, Paul J.M., Scholten, Johan.

▼ Wireless multi-hop ad hoc networks are self-organizing networks that can be spontaneously deployed without any need of fixed infrastructure. In order to enable communication, network nodes share their resources to store and forward other nodes' data packets. However, the current hardware technology significantly limits the battery power network nodes run on. As a result, designing energy-efficient networking algorithms is of paramount importance for the viability of this type of networks. In the present thesis, we study networking algorithms that rely on packet redundancy to provide fair communication. This approach can significantly increase the number of transmissions and have a severe impact on the energy efficiency. Our main goal is to devise novel algorithms that efficiently handle packet redundancy in order to reduce the related energy costs without compromising the overall performance. We focus on two well-known fields; broadcasting in mobile ad hoc networks (MANETs) and routing in opportunistic networks (OppNets). In the first part, we examine energy-efficient broadcasting in MANETs. The latest trend in this field combines traditional broadcast schemes with network coding. Besides enhancing the energy efficiency through the reduction of transmissions, this synergy also increases the resilience to loss and improves security. Initially, we focus on XOR-based broadcasting and reveal cases where the well-established approach suffers performance breakdowns. We attribute this behavior to an essential component of the underlying broadcast algorithm that is inherently incompatible with network coding. To tackle the problem, we introduce a novel coding-friendly broadcast algorithm. Furthermore, for the first time, we use XOR coding as a mechanism not only for enhancing energy efficiency but also for reducing the end-to-end-delay. Through extensive simulations, we demonstrate the effectiveness of the proposed algorithm on improving the energy efficiency, delivery delay and utilization of network resources. Then, we focus on RLNC-based broadcasting and introduce an analytical model that captures the performance of coding-based broadcast schemes. We observe that the traditional approach to combine RLNC and probabilistic forwarding significantly impacts the performance of RLNC. To this end, we design a novel RLNC-based broadcast algorithm that for the first time applies RLNC over CDS-based broadcasting. The proposed algorithm provides a more systematic pruning of redundant transmissions without compromising RLNC's efficiency. We also investigate the generation management that is a key issue in RLNC and introduce a new distributed scheme that is suitable for mobile environments. Finally, through extensive simulations, we show that the proposed algorithm outperforms XOR-based as well as RLNC-based schemes even when global knowledge is used for managing packet generations. In the second part of the thesis, we investigate energy-efficient routing in OppNets. The prominent routing strategy in coping with intermittent…
