▼ Wireless Sensor Networks (WSNs) are ad-hoc wireless networks for small form-factor embedded nodes with limited memory, processing and energy resources. Certain applications, like industrial automation and real-time process monitoring requires time synchronized reliable network protocol. Current work for WSNs provides either time synchronized with low reliability (WirelessHART) or reliable network without time synchronization (Collection Tree Protocol). The Collection Tree Protocol (CTP) provides the reliability from 94.7% to 99.9% for CSMA-CA based MAC layer. This paper addresses channel hopping, a class of frequency diverse communication protocol in which subsequent packets are sent over different frequency channels. Channel hopping combats external interference and persistent multipath fading, two of the main causes of failure along a communication link. Channel hopping technique leads to a high reliable and efficient protocol which is specified by HART Communication Foundation and named as WirelessHART. WirelessHART Data-Link layer designed based on TDMA and CSMA-CA mechanism. By implementing the CTP over WirelessHART Data-Link layer, the reliability of the network protocol can be improved compare to actual CTP standard implementation. This thesis describes the design and implementation of Collection Tree Protocol over WirelessHART Data-Link layer. The implementation is done using TinyOS, nesC programming language using Crossbow TelosB CC2420 radio chip nodes. The results and experiments show the evaluation of the system prototype.

▼ The last decade has witnessed a rapid surge in application of body sensor net-works, especially in the domains of military, healthcare and fitness. In suchnetworks, wearable wireless sensor devices are used to measure and communi-cate a subject’s vital signs (such as heart rate, body temperature, blood glucoselevel, etc.) Security, in this context, is a critical issue as these devices deal withpersonal health data, requiring strict privacy and confidentiality. However, tra-ditional secret-key generation mechanisms (such as Diffie-Hellman) are typicallycomputation and power intensive and not suitable for resource-constrained sen-sor devices. This thesis aims at realizing a practical and low-cost secret keygeneration mechanism for wearable sensor devices.First, we investigate a secret key generation mechanism that extracts sharedsecret keys using properties of the near-body wireless channel between two com-municating parties. For a fully body-worn scenario, our experimental results,using off-the-shelf IEEE 802.15.4 devices, indicate that this approach is feasiblefor dynamic scenarios where communicating devices are placed in non-line-of-sight positions on the body. We also suggest an enhancement for existing keygeneration mechanisms using a filtering mechanism which considerably reducesbit mismatches.Second, we employ a channel hopping technique to decorrelate secret bit ex-traction. Due to fast sampling rates, successive samples of channel properties arecorrelated in time, yielding weak keys with reduced entropy. To overcome this, weuse channel hopping to increase channel diversity. We conduct extensive experi-ments to show that channel hopping increases frequency diversity and effectivelydecorrelates successive channel samples and thereby dramatically improving thestrength of the secret key. Furthermore, we identify key parameters affectingperformance, namely channel spacing, the number of available channels, and useractivity. We show that it is possible to devise an optimal hopping strategy tomaximize the benefit by balancing between channel spacing and the number ofchannels for high frequency and temporal diversity.In this thesis, we describe, implement and validate our solutions in real body-worn scenarios. It is hoped that our effort contributes to the research and devel-opment of usable body sensor networks.

▼ Cognitive radio (CR) is seen as one of the enabling technologies for realizing a new regulatory spectrum management paradigm, viz. opportunistic spectrum sharing (OSS). In the OSS paradigm, unlicensed users (a.k.a. secondary users) opportunistically operate in fallow licensed spectrum on a non-interference basis to licensed users (a.k.a. incumbent or primary users). Incumbent users have absolute priority in
licensed bands, and secondary users must vacate the
channel where incumbent user signals are detected. A CR network is composed of secondary users equipped with CRs and it can coexist with incumbent users in licensed bands under the OSS paradigm. The coexistence between incumbent users and secondary users is referred to as incumbent coexistence, and the coexistence between CR networks of the same type is referred to as self-coexistence.
In this dissertation, we address three coexistence-related problems at the medium access
control (MAC) layer in CR networks: (1) the rendezvous (control
channel) establishment
problem, (2) the
channel assignment problem in an ad hoc CR network, and (3) the spectrum sharing problem between infrastructure-based CR networks, i.e., the 802.22 wireless regional area networks (WRANs). Existing MAC layer protocols in conventional wireless networks fail to adequately address the key issues concerning incumbent and self coexistence that emerge in CR networks. To solve the rendezvous establishment problem, we present a systematic approach, based on quorum systems, for designing
channel hopping protocols that ensure a pair of CRs to "rendezvous" within an upper-bounded time over a common
channel that is free of incumbent user signals. In a single radio interface, ad hoc CR network, we propose a distributed
channel assignment scheme that assigns channels at the granularity of "segments" for minimizing the
channel switching overhead. By taking into account the coexistence requirements, we propose an inter-network spectrum sharing protocol that enables the sharing of vacant TV white space among coexisting WRANs. Our analytical and simulation results show that these proposed schemes can effectively address the aforementioned MAC layer coexistence problems in CR networks.

▼ Rendezvous is a fundamental process establishing a communication link on common
channel between a pair of nodes in the cognitive radio networks. How to reach rendezvous efficiently and effectively is still an open problem. In this work, we propose a guaranteed cycle lengths based rendezvous (CLR) algorithm for cognitive radio networks. When the cycle lengths of the two nodes are coprime, the rendezvous is guaranteed within one rendezvous period considering the time skew between the two nodes. When T
i and T
j are not coprime, i.e., T
i=T
j, the deadlock checking and node IDs are combined to decide the time point and the way to independently change the cycle length on each node to guarantee rendezvous. In detail, as long as the deadlock situation is detected based on the threshold, each node can independently change its cycle length be based on the current checking bit of the node ID. The threshold used for deadlock checking is defined as the length of the maximum possible rendezvous period between the two nodes. As long as the current checking bits between the two nodes are different, the rendezvous will be reached in the following rendezvous period, The theoretical analysis also proves the guarantee of the CLR algorithm under both the two cases. We use three metrics: success rate of rendezvous, expected time to rendezvous and
channel load to conduct simulation studies. The simulation results show that the CLR algorithm always has higher successful rendezvous rate of 100%, and stable and low expected time to rendezvous compared to the HH algorithm. In addition, the
channel loads are smoothly distributed on all channels with CLR, while HH algorithm depends on the channels with smaller IDs.

▼ As more and more wireless applications/services emerge in the market, the already heavily crowded radio spectrum becomes much scarcer. Meanwhile, however,as it is reported in the recent literature, there is a large amount of radio spectrum that is under-utilized. This motivates the concept of cognitive radio wireless networks
that allow the unlicensed secondary-users (SUs) to dynamically use the vacant radio spectrum which is not being used by the licensed primary-users (PUs).
In this dissertation, we investigate protocol design for both the synchronous and asynchronous cognitive radio networks with emphasis on the medium access control (MAC) layer. We propose various spectrum sharing schemes, opportunistic packet scheduling schemes, and spectrum sensing schemes in the MAC and physical (PHY) layers for different types of cognitive radio networks, allowing the SUs to opportunistically utilize the licensed spectrum while confining the level of interference to the range the PUs can tolerate. First, we propose the cross-layer based multi-
channel MAC protocol, which integrates the cooperative spectrum sensing at PHY layer and the interweave-based spectrum access at MAC layer, for the synchronous cognitive radio networks. Second, we propose the
channel-
hopping based single-transceiver MAC protocol for the hardware-constrained synchronous cognitive radio networks, under which the SUs can identify and exploit the vacant channels by dynamically switching across the licensed channels with their distinct
channel-
hopping sequences. Third, we propose the opportunistic multi-
channel MAC protocol with the two-threshold sequential spectrum sensing algorithm for asynchronous cognitive radio networks. Fourth, by combining the interweave and underlay spectrum sharing modes, we propose the adaptive spectrum sharing scheme for code division multiple access (CDMA) based cognitive MAC in the uplink communications over the asynchronous cognitive radio networks, where the PUs may have different types of
channel usage patterns. Finally, we develop a packet scheduling scheme for the PU MAC protocol in the context of time division multiple access (TDMA)-based cognitive radio wireless networks, which is designed to operate friendly towards the SUs in terms of the vacant-
channel probability.
We also develop various analytical models, including the Markov chain models, M=GY =1 queuing models, cross-layer optimization models, etc., to rigorously analyze the performance of our proposed MAC protocols in terms of aggregate throughput, access delay, and packet drop rate for both the saturation network case and non-saturation network case. In addition, we conducted extensive simulations to validate our analytical models and evaluate our proposed MAC protocols/schemes. Both the numerical and simulation results show that our proposed MAC protocols/schemes can significantly improve the spectrum utilization efficiency of wireless networks.

▼ Cognitive radio (CR) is a promising technique to enhance the spectrum utilisation by enabling the CR users to opportunistic access the spectrum holes or channels. CR ad hoc network is a multi-
channel environment where
channel status changes over time depending on primary users’ (PUs) activities. Analogous to control
channel establishment in traditional multi-
channel ad hoc network, rendezvous in CR ad hoc network is one of the most important processes for a pair of unknown CR users to initiate communication. Most of the existing research have utilised a common control
channel to achieve rendezvous. This utilization generates
channel saturation, extreme transmission overhead of control information, and a point of vulnerability. The traditional designs for rendezvous protocols do not support an ad-hoc CR network
model. Therefore, this thesis is focused on improving control
channel establishment to solve the rendezvous problem and support further CR ad-hoc networks. This thesis proposes a new
channel hopping (CH) scheme called extended torus quorum
channel hoping (ETQCH) for asymmetric and asynchronous pair wise RDV in CR ad-hoc networks. The ETQCH employs
channel ranking information for allocating more slots to high-rank channels than low-rank ones. The system dynamically
updates the CH sequence by replacing channels from both the licensed and unlicensed bands to protect intermittent PUs.
Channel hopping sequence scheme is a mathematical concept to guarantee overlap between two CR users. A successful RDV establishment depends on successful
channel probe or control packet exchange which is a MAC layer issue. Therefore, a new MAC protocol named cognitive radio rendezvous (CR-RDV) MAC is proposed to facilitate the multiuser contention in CR ad-hoc networks. CR-RDV is developed by re-defining the traditional backooff procedure and incorporating a sensing period immediately after the request-to-send; the incumbent PU’s transmission is protected and blocking problems are resolved. The analysis and simulation results show the potential to minimise service interruption, block node problems, and efficiently utilise dynamic radio resources. The thesis also provides a guideline for CR system planners to design and deployment of dense networks with active PUs.

▼ Face à une demande sans cesse croissante de haut débit et d’adaptabilité des systèmes existants, qui à son tour se traduit par l’encombrement du spectre, le développement de nouvelles solutions dans le domaine des communications sans fil devient nécessaire afin de répondre aux exigences des applications émergentes. Parmi les innovations récentes dans ce domaine, l’ultra large bande (UWB) a suscité un vif intérêt. La radio impulsionnelle UWB (IR-UWB), qui est une solution intéressante pour réaliser des systèmes UWB, est caractérisée par la transmission des impulsions de très courte durée, occupant une largeur de bande allant jusqu’à 7,5 GHz, avec une densité spectrale de puissance extrêmement faible. Cette largeur de bande importante permet de réaliser plusieurs fonctionnalités intéressantes, telles que l’implémentation à faible complexité et à coût réduit, la possibilité de se superposer aux systèmes à bande étroite, la diversité spatiale et la localisation très précise de l’ordre centimétrique, en raison de la résolution temporelle très fine.Dans cette thèse, nous examinons certains éléments clés dans la réalisation d'un système IR-UWB intelligent. Nous avons tout d’abord proposé le concept de radio UWB cognitive à partir des similarités existantes entre l'IR-UWB et la radio cognitive. Dans sa définition la plus simple, un tel système est conscient de son environnement et s'y adapte intelligemment. Ainsi, nous avons tout d’abord focalisé notre recherché sur l’analyse de la disponibilité des ressources spectrales (spectrum sensing) et la conception d’une forme d’onde UWB adaptative, considérées comme deux étapes importantes dans la réalisation d'une radio cognitive UWB. Les algorithmes de spectrum sensing devraient fonctionner avec un minimum de connaissances a priori et détecter rapidement les utilisateurs primaires. Nous avons donc développé de tels algorithmes utilisant des résultats récents sur la théorie des matrices aléatoires, qui sont capables de fournir de bonnes performances, avec un petit nombre d'échantillons. Ensuite, nous avons proposé une méthode de conception de la forme d'onde UWB, vue comme une superposition de fonctions B-splines, dont les coefficients de pondération sont optimisés par des algorithmes génétiques. Il en résulte une forme d'onde UWB qui est spectralement efficace et peut s’adapter pour intégrer les contraintes liées à la radio cognitive. Dans la 2ème partie de cette thèse, nous nous sommes attaqués à deux autres problématiques importantes pour le fonctionnement des systèmes UWB, à savoir la synchronisation et l’estimation du canal UWB, qui est très dense en trajets multiples. Ainsi, nous avons proposé plusieurs algorithmes de synchronisation, de faible complexité et sans séquence d’apprentissage, pour les modulations BPSK et PSM, en exploitant l'orthogonalité des formes d'onde UWB ou la cyclostationnarité inhérente à la signalisation IR-UWB. Enfin, nous avons travaillé sur l'estimation du canal UWB, qui est un élément critique pour les récepteurs Rake cohérents. Ainsi, nous avons…

▼ Une communication est impulsive chaque fois que le signal portant des informations est intermittent dans le temps et que la transmission se produit à rafales.

▼ In wireless networks, it is required to
change an operating frequency as part of the radio resource
management due to strong interference or system requirements of
accessing radio resources. In this thesis, we propose two radio
resource management schemes in wireless sensor networks and
cognitive radio networks. In the proposed schemes, sensor networks
switch to a new
channel when they detect strong interference and a
secondary user in cognitive radio networks moves to a new spectrum
when it detects or predicts the presence of a primary
user. In the first part of the thesis, we propose
a
channel hopping scheme which can be used for interfered wireless
networks. With the additive functionality of a
channel hopping
mechanism on the sensor network stack, we aim to avoid the
interference from other sensor nodes and wireless technologies on
ISM band as well as avoid narrow-band jamming. For simple and
reliable
channel hopping, we introduce an Adaptive
Channel Hopping
scheme, a spectrum environment aware
channel hopping scheme, for
interference robust wireless sensor networks. When the
channel
status becomes suboptimal to communicate, the adaptive
channel
hopping lets the sensors switch to a new clean
channel. To generate
channel selection/scanning orders which minimize
channel hopping
latency, we use two parameters which are link quality indicator
(LQI) and
channel weighting. The proposed adaptive
channel hopping
scheme is evaluated through simulations. Simulation results
indicate that the proposed scheme significantly reduces the
channel
hopping latency and selects the best quality
channel. In the second part of the thesis, we
propose a novel approach to spectrum management in cognitive radio
networks. To support flexible use of spectrum, cognitive radio
networks employ spectrum mobility management schemes, including
spectrum handoff, which refers to the switching of the operating
spectrum due to changes in licensed (primary) user activity.
Spectrum handoff inevitably results in temporary disruption of
communication for the unlicensed (secondary) user operating in a
licensed band opportunistically. Minimization of secondary user
service disruption is an important objective of spectrum handoff
schemes. In this thesis, we introduce a new type of spectrum
handoff called Voluntary Spectrum Handoff assisted by a primary
user spectrum usage estimation scheme. The two mechanisms proposed
under voluntary spectrum handoff method estimate opportune times to
initiate unforced spectrum handoff events to facilitate setup and
signaling of alternative channels without having communication
disruption, which occurs when a secondary user is forced out of an
operating spectrum due to primary user activity. To estimate
primary user spectrum usage,
channel usage information is
continuously updated with a fixed spectrum sensing window and a
variable history window. Proposed voluntary spectrum handoff and
primary usage estimation schemes are evaluated through extensive
simulations. Simulation results indicate that the proposed…

▼ Due to correlated fading in frequency
hopping (FH) wireless communication systems, it is possible to predict the future
channel state information (CSI) for one frequency based on the
channel observations of other frequencies. As a result, the performance of slow FH systems can be improved by utilizing adaptive transmission techniques. We propose the optimal Minimum Mean Square Error (MMSE) Long Range Prediction algorithm for slow FH systems that employ coherent detection. A recursive autocorrelation update method and a simplified prediction algorithm are explored to reduce the complexity. Statistical model of the prediction accuracy is developed and used in the design of the reliable adaptive transmission systems. We investigate the performance of adaptive transmission for high-speed data transmission in SFH systems based on the proposed Long Range Prediction algorithms. For slow frequency
hopping communications in the presence of partial-band interference, we propose to employ adaptive transmitter frequency diversity and adaptive modulation to mitigate the effects of partial-band interference and fading. Both standard Jakes model and realistic physical model are used to test the performance. Analysis and simulation results show that significant performance gains can be achieved relative to non-adaptive methods.

▼ During the last decade, wireless technologies have revolutionized the industrial automation sector by enabling wireless sensing and actuation for industrial applications. Most of these recently developed industrial standards are built on top of IEEE802.15.4 interface, which uses 2.4GHz frequency band for communication. Because of the wide use, reliable communication with low latency cannot always be guaranteed on this frequency band. While satisfying the requirements of monitoring applications quite well, current industrial standards have several limitations to address the requirements of time-critical control applications. For instance, owing to the use of a centralized network management scheme, widely used industrial standards such as WirelessHART and ISA100.11a cannot handle network disturbances in a real-time manner. Moreover, the I/O devices (sensors and actuators) in these systems have to go through a complex network joining process, which takes a lot of time and energy. The network devices in industrial applications are typically expected to run for a long time without maintenance. Replacing batteries and main powering of these nodes are often not practical in industrial environments. To address this issue, energy harvesting technologies are becoming popular as an alternative power source for the industrial I/O devices. However, present energy harvesters can only produce a little amount of energy that forces the harvester powered I/O devices to shut down frequently. Consequently, these I/O devices need to re-join the network to resume their task, which consumes additional energy. Clearly, this is a huge overhead for resource constraint I/O devices. To deal with the above mentioned limitations of existing industrial systems, we propose two hierarchical network management schemes where blocks of communication resources are delegated to the routers to locally manage the I/O devices. The proposed schemes are able to cope with the network disturbances quickly with low overhead. Next, we propose a fast network joining scheme for I/O devices that is able to reduce the network joining overhead and make the network more suitable for harvester powered I/O devices. In addition, we propose a data publication scheme for the harvester powered I/O devices by utilizing spatial diversity that can improve the communication reliability. Last but not least, with the advances in energy harvesting technologies, a new industrial application class called fit-and-forget system, in which I/O devices are only powered by energy harvesters, is attracting much attention. To address the requirements of such I/O devices with strict energy budget, we propose an asynchronous communication scheme that allows harvester powered I/O devices to transmit their data whenever they harvest enough energy.
