Full textThe main goal of this thesis is to propose efficient adaptive communication mechanisms using cross layer interactions in IEEE 802. 11 WLANs. First, we present a detailed performance evaluation of 802. 11a/b PHY layer transmission modes. The second contribution of the thesis concerns 802. 11 MAC/PHY layers modelling. An analytical model that accounts for the positions of stations with respect to the access point while evaluating the performance of 802. 11 MAC layer, has been proposed. The third contribution of the thesis concerns rate adaptation mechanisms and especially cross layer algorithms between MAC and PHY layers. An adaptive rate selection algorithm, called AARF for low latency systems that improves upon ARF to provide both short-term and long-term adaptation has been proposed. In this field, we also present a new rate adaptation algorithm designed for high latency systems named AMRR that has been implemented and evaluated on an AR5212-based device. We then propose a closed-loop, dynamic rate selection algorithm that can be implemented in all 802. 11a/b/g compliant wireless local area networks. This algorithm called CLARA is a culmination of the best attributes of the transmitter-based ARF and the RBAR control mechanisms with additional practical features to facilitate multipath fading channel sensing and feedback control signalling. The last contribution of the thesis is on the optimization of real time multimedia transmission over 802. 11 based networks. In particular, we propose a simple and efficient cross layer mechanism, called MORSA, for dynamically selecting the transmission mode considering both the channel conditions and characteristics of the media

Full textLe but de cette thèse a été l'étude et la proposition de solutions pour gérer la mobilité de l'utilisateur dans des réseaux utilisant le standard IEEE 802. 11. Dans cette thèse, nous avons développé deux architectures. Dans la première, nous avons introduit une architecture sécurisée pour gérer le roaming des nœuds mobiles dans les réseaux sans fil. Le but de cette architecture SMMArc (Service Mobility Management Architecture) a consisté à offrir des services à l'utilisateur d'après son profil. La deuxième architecture a été développée de manière à gérer des connexions TCP lorsque les nœuds mobiles changent de domaine en cours de communication. Cette architecture ATHOMIC (Architecture managing Tcp Handoff Over Mobile Ip Connections) a permis de réduire la probabilité de perte des segments lorsque les nœuds mobiles changent de domaines IP

Full textStudy of the IEEE 802. 11 standard un ad hoc networks context: from simulation to experimentation. The mobiles composing ad hoc networks do not rely on any fixed infrastructure and organise themselves depending on nodes movements. This research area is quite recent, and most of the work concerns routing. Because of its commercial availability and its ease of use, IEEE 802. 11 standard (Wi-Fi) is generally chosen to develop and test ad hoc routing protocols. But 802. 11 has not been originally designed for multi-hops networks and has limitations in this context that we intend to highlight. Using simulations then real world experimentations, we bring up many problems ranging from medium access equity to transmission range and environment impact. With its detailed study of these phenomena, this PhD has an impact in particular over ad hoc routing protocols and the way they are designed, but also over upper layers protocols, TCP being the first of them

Full textAvec l'émergence des applications multimédia dans les réseaux ad hoc, des garanties de la qualité de service QoS sont de plus en plus exigées. Le premier obstacle à franchir consiste en la connaissance de l'état du réseau en terme de délai ou de bande passante ou tout autre critère, que ce soit par modélisation ou par le biais de mesures. Dans le cadre de cette thèse, nous nous sommes intéressés à l'étude du délai et du routage avec délai dans des réseaux sans fil ad hoc particuliers que sont les réseaux 802. 11. Nous avons tout d'abord modélisé le mode d'accès DCF du protocole 802. 11. Nous avons ensuite déduis les délais moyens et les distributions de délai à un saut et multi sauts. Grâce au simulateur ns-2, nous avons pu étudié et validé notre modèle analytique. Par ailleurs, nous avons montré que les délais dans les réseaux 802. 11 suivent une loi puissance. Nous avons proposé une extension du protocole de routage proactif OLSR, que nous avons appelé DOLSR, pour le support du délai. DOLSR calcule les routes qui minimisent le délai moyen de bout en bout en se basant sur l'évaluation périodique locale du délai à un saut effectuée grâce à la modélisation et la diffusion de ce dernier via des paquets particuliers. Nous avons implémenté DOLSR sous ns-2 et étudié ses performances en terme de délai et de perte de paquets. Finalement, nous avons proposé, comme alternative au routage avec délai moyen, un routage avec distribution de délai. Ce problème étant NP complet, nous avons utilisé les résultats de l'analyse asymptotique du délai pour proposer une solution

Full textThis dissertation focuses on the design, implementation, and evaluation of 802. 11-based cross-layer mechanisms for the enhancement of the support of the QoS feature. Before the cross-layer study, we have also explored the idea of enhancing separately a communications layer; namely the existing 802. 11e MAC protocol which is designed for the QoS support. Although the improvements achieved, this study shows the limitations of the layered architecture that demonstrated its good performance in wired networks. Due to the large number of cross-layer cooperation possibilities, we emphasize, in this work, on the cooperation between the MAC and the network layers. We believe that the cooperation between these two layers provides better performance improvement than the cooperation between other layers. In particular, we focus on the problem of routing data packets in a way that takes into account channel contention level, network characteristics, and higher-layer protocol requirements. We address the optimal routing with regard to links stability, average end-to-end delay, and energy conservation with and without assistance/initiation from the network. We design several cross-layer mechanisms that aim to overcome the issue of routing in MANETs while enhancing important QoS metrics (path stability, energy consumption, end-to-end delay, etc. ). To this end, we extract the adequate parameters from both MAC and network layers and adapt them to provide QoS enhancement based on new inter-layer cooperation algorithms. Furthermore, we identify the challenges that face the cross-layer architectures comparing to the traditional layered architecture for enhancing communication protocols

Full textNext-generation Wireless Local Area Networks (WLAN) are involved to support a variety of services and traffic types. Among these services real-time applications, unlike Web and data transfert, requiere a strict Quality of Service (QoS) support such as: (i) low end-to-end delays; (ii) bandwidth guarantee and low drop rate. Since the IEEE 802. 11 standard fails to introduce differentiation between traffic classes, providing QoS in 802. 11-based network is very challenging. Indeed, both MAC layer and Physical layer designed by the IEEE 802. 11 standard support only best-effort transmission. Usually, the IEEE 802. 11 standard features the specifications for the two OSI's lower layers (MAC and Physical). The Medium Access Control (MAC) introduces two medium access protocols that are conceptly different: (i) Distributed Coordination Function (DCF) is a contention-based access mechanim executed independatly at each wireless station; (ii) Point Coordination Function (PCF) is a pooling-based mechanism that needs a central station to regulate the wireless traffic. The popularity of IEEE 802. 11 is mainly due to DCF, whereas PCF is barely implemented in today's products due to its complexity and inneficiently for the data transmission. Further, unlike DCF that can be deployed in every network configuration (ad-hoc and infrastructure), PCF is designed only for infrastructure-based configuration. By considering that MAC layer is the key element that provides QoS support in 802. 11-based wireless networks, our work through this thesis is to study and improve the legacy MAC layer and more especially the DCF access mechanism. Accordingly, we leverage the MAC's capability to support real-time's QoS requirements. The contributions of this thesis are organized onto two axes: •Improve the Backoff Binary Backoff (BEB) algorithm employed by DCF in two hostils environements: (i) when the newtwork operates with high collisions (high network load); (ii) when the network operates in noisy environements (high Bit Error Rate). •Study the concepts and the fesability of QoS in the 802. 11 MAC layer through the introduction of: (i) a new MAC protocol featuring QoS supports; (ii) a cross-layer architecture involoving the H. 264 encoder and the 802. 11e MAC layer aiming at ensure a robust video transport over WLAN

Full textMobile Ad hoc Network (MANET) is an autonomous system of mobile nodes connected by wireless links. They require no fixed infrastructure such as base station to operate; therefore, it is an attractive networking option for connecting mobile devices quickly and spontaneously. The nodes themselves address topology changes due to the mobility, the arrival or the departure of nodes. Today, several applications general multimedia data or rely on the proper transmission of sensitive control traffic. These applications may benefit from a quality of service (QoS) support. Therefore, this field has been extensive/y studied and more and more QoS solutions are proposed for ad hoc networks. During my thesis, I focus on one of the fundamental resources, the bandwidth. Estimating the remaining bandwidth at a given time an in a given part of the network is tricky, as the medium is shared between close nodes in a wireless network. This implies that computation of the available bandwidth between two neighbor nodes requires identification of all the emitter's potential contenders and of all the receiver's potential jammers. I propose therefore a new technique to estimate residual bandwidth in ad hoc networks which present good performances. From this estimation, i have also developed a management scheme for QoS and Best Effort flows in order to increase the acceptance rate of QoS flows. Finally, we also compute an evaluation of end-to-end delay in these ad hoc networks
