Full textMultitask learning has received considerable attention in signal processing and machine learning communities. It aims at simultaneously learning several related tasks other than the traditional single-task problems. There also have witnessed a wide spectrum of data processing problems that are network- or graph-structured and require adaptation ability to streaming data and time-varying dynamics. Distributed adaptive learning strategies over networks enable a collection of interconnected agents to accomplish a certain task, such as parameter estimation, collaboratively through local computation and cooperation among neighboring agents. Further, they endow the agents with continuous adaptation and learning ability to track possible drifts in the underlying model. Despite the heterogeneous nature and the fact that each agent may solve a different task in multitask network, it could still benefit from a collaboration between agents to improve the estimation accuracy by leveraging the relations and capitalizing on inductive transfer between them. The objective of this thesis is to devise and analyze multitask adaptive learning strategies over networks and graphs. First, we consider multitask estimation problems where each agent is interested in estimating its own parameter vector and where the parameter vectors at neighboring agents are related linearly according to a set of constraints. Based on the penalty method, an unconstrained optimization problem is reformulated and a distributed algorithm is derived. The behavior of the algorithm in the mean and in the mean-square-error sense is analyzed. Next, we relax the local constraints assumption and consider the multitask problem with non-local constraints. We devise the distributed algorithm by employing a multi-hop relay protocol across the agents. We prove that the algorithm will continue to converge and provide theoretical performance analysis. In the third part, we extend the distributed learning strategies to the emerging graph signal processing applications where the signal itself is network-structured. Several graph diffusion LMS strategies are proposed to cope with streaming graph signals. We also extend the multitask model to graph filters and propose an on-line clustering mechanism. Last, we consider the problem of modeling graph signals by using a combination of multiple graph filters. An efficient algorithm is proposed to simultaneously learn coefficients of multiple graph filters and perform model selection. Simulation and numerical results are provided to illustrate the effectiveness of all proposed algorithms and validate the theoretical analyses

Full textDriven by the increasing demand for multimedia services in broadband Internet networks, WIMAX technology has emerged as a competitive alternative to the wired broadband access solutions. The IEEE 802.16 is a solution that provides high throughput by ensuring a satisfactory QoS. In particular, it is suitable for multimedia applications that have strict QoS constraints. However, the users’ heterogeneity and diversity in terms of bandwidth, radio conditions and available resources, pose new deployment challenges. Indeed, multimedia applications need to interact with their environment to inform the access network about their QoS requirements and dynamically adapt to changing network conditions.In this context, we propose two solutions for video streaming over 802.16 networks based on Cross-Layer approach. We are interested in both unicast and multicast transmissions in uplink and downlink of one or more WIMAX cells.First, we proposed an architecture that enables Cross-Layer adaptation and optimization of video streaming based on available resources. We defined the entity CLO (Cross-Layer Optimizer) that takes benefits from service flow management messages, exchanged between BS and SS, at the MAC level, to determine the necessary adaptations / adjustment to ensure optimal delivery of the application. Adaptations occur at two epochs, during the admission of the video stream and during the streaming phase. The performance analysis, performed through simulations, shows the effectiveness of the CLO to adapt in a dynamic way, the video data rate depending on network conditions, and thus guarantee an optimal QoS.Second, we proposed a solution that enables IP multicast video delivery in WIMAX network. This solution allows finding the compromise between the diversity of end-user requirements, in terms of radio conditions, modulation schemes and available resources, along with the SVC hierarchy video format, to offer the best video quality even for users with low radio conditions. Indeed, we define a multicast architecture that allows each user to get a video quality proportionally to its radio conditions and its available bandwidth. Towards this end, several IP multicast groups are created depending on the SVC video layers. Subsequently, our solution allows optimizing the use of radio resources by exploiting the different modulations that can be selected by the end-users

Full textThe advent of Web 2.0, user-centered, has given rise to a significant amount of information (personal, collective, shared, "loved", etc.). This information is a way to help users and guide them to the information sought. However, this quantity makes access to shared information more and more difficult, given the diversity of content that may interest the user. Disorientation of the user is one of the main problems related to social media. To overcome such problem, adaptation is a standard solution that can be applied in a social context. With the evolution of these social networks, new concepts appear such as social navigation, which is a way to navigate while being influenced by other users in the network: Another important concept is that of "tag". This term is defined as social annotations created by users and associated to resources. Navigation can be therefore carried out by both links and tags. Adapting social navigation means making it more targeted for each user according to their interests. In practice, this can be done by recommending tags to each user, so he can follow or not. To adapt the social navigation, we must ensure proper detection of the user's interests and taking into account their evolution. However, we are faced with some problems: i) the detection of interest, since they can be derived from several social resources (friends, resources, tags, etc.). Their relevance is primordial to ensure adequate adaptation result. ii) updating the user profile. Indeed, the social user, is characterized by its great social activity, and therefore its interests should reflect its "real" interest each time period in order to achieve a reliable adaptation. To solve the problems affecting the quality of adaptation of social navigation quoted above, we first proposed a method for detecting the user's interests. This proposal aims to overcome the detection of irrelevant interests issues. This approach analyzes the user tags depending on the content of their respective resources. Unlike most research, who do not consider the accuracy of tags with the contents of resource, the accuracy reflects whether the user is really interested with the content or not. This is done by querying the user's network and analysis of the user annotation behavior. The approach is based on the assumption that a user annotates the resource by tags reflecting the content of this resource better reflects its "true" interests. Following the proposal of the interests of detection approach, we conducted second, the treatment of the problem of updating these interests. We were interested to the user profile enrichment techniques, performed by adding interests deemed relevant at a given time. The enrichment in a social context is performed according to social information such as neighbours who share the user behaviors in common, according to the user annotation behavior, and according to the metadata annotated resources. The choice of such information shall follow the study of their influence on the changing interests of the user. The approach we used enrichment propose recommendations (tags) according to the new tags added to the user profile. Both contributions were tested on the social database Delicious. They showed a sizeable accuracy rate. They have also proven their efficiency compared to conventional methods. In addition, the rate of ambiguity associated with the tags has been greatly reduced, thanks to the implicit filtering of irrelevant tags relative to resource content

Full textLes techniques de transmission coopérative dans les réseaux sans fil concernent les méthodes dont l'objectif principal est d'améliorer la fiabilité de la transmission d'information entre la source et la destination en exploitant des terminaux intermédiaires appelés relais. L'objectif principal de cette thèse est de proposer un mécanisme efficace d'adaptation de liens en utilisant les techniques inter-couches dans les réseaux coopératifs. L'évaluation des performances des modules coopératifs, en utilisant soit un seul relais soit plusieurs relais, est présentée. Par ailleurs, la fiabilité de la transmission peut être améliore��e par le déploiement de codage espace-temps distribué (DSTC) dans la coopération. De plus, un mécanisme de sélection de relais et d'adaptation de mode physique a été développé pour améliorer le débit efficace pendant la transmission. En analysant la valeur du rapport signal à bruit (SNR) de bout en bout pour les transmissions coopératives, le protocole coopératif qui assure le taux optimal de transmission peut alors être déterminé. Finalement, grâce à une spécification de la couche MAC intégrant la gestion de la coopération, le choix du meilleur relais et l’adaptation de liens sont présentés. Cette thèse montre, d'une part, que la capacité de lien dans les réseaux coopératifs peut être améliorée lorsque les modes physiques du relais sont bien adaptés aux conditions des canaux, et d'autre part, que des stratégies inter-couches efficaces peuvent fournir un meilleur support de la qualité de service

Full textThe main goal of the thesis is to design an Energy Proportional Network by taking intelligent decisions into the network such as switching on and off network components in order to adapt the energy consumption to the user needs. Our work mainly focuses on reducing the energy consumption by adapting the number of APs that are operating to the actual user need. In fact, traffic load varies a lot during the day. Traffic is high in urban areas and low in the suburb during day work hours, while it is the opposite at night. Often, peak loads during rush hours are lower than capacities of the networks. Thus they remain lightly utilized for long periods of time. Thus keeping all APs active all the time even when the traffic is low causes a huge waste of energy. Our goal is to benefit from low traffic periods by automatically switch off redundant cells, taking into consideration the actual number of users, their traffic and the bandwidth requested to serve them. Ideally we wish to do so while maintaining reliable service coverage for existing and new coming users. First we consider a home networking scenario. In this case only one AP covers a given area. So when this AP is switched off (when no users are present), there will be no other AP to fill the gap of coverage. Moreover, upon the arrival of new users, no controller or other mechanism exists to wake up the AP. Consequently, new arriving users would not be served and would remain out of coverage. The study of the state of the art allowed us to have a clear overview of the existing approaches in this context. As a result, we designed a platform to investigate different methods to wake up an AP using different technologies. We measure two metrics to evaluate the Switching ON/OFF process for the different methods. The first is the energy consumed by the AP during the three phases it goes through. The second is the delay of time for the AP to wake up and be operational to serve the new users. In the second case we consider a dense network such as the ones found in urban cities, where the coverage area of an AP is also covered by several other APs. In other words, the gap resulting from switching off one or several APs can be covered by other neighbouring ones. Thus the first thing to do was to evaluate the potential of switching off APs using real measurements taken in a dense urban area. Based on this collected information, we evaluate how many APs can be switched off while maintaining the same coverage. To this end, we propose two algorithms that select the minimum set of APs needed to provide full coverage. We compute several performance parameters, and evaluate the proposed algorithms in terms of the number of selected APs, and the coverage they provide
