Available in PDF, EPUB and Kindle. Book excerpt: Résumé Dans les réseaux ad hoc et les réseaux de capteurs, certains nœuds disposent d'une autonomie d'énergie limitée. Il s'avère alors très important de gérer efficacement cette énergie afin de maximiser la durée de vie du réseau. Nous avons classé les solutions en 4 classes : 1) contrôle de topologie, 2) routage économe en énergie, 3) ordonnancement de l'activité des nœuds et 4) réduction du volume des donnée transférées. Notre contribution consiste en un routage économe en énergie nommé EOLSR et un ordonnancement de l'activité des nœuds nommé SERENA. EOLSR consiste à calculer la route qui minimise l'énergie consommée de bout-en-bout tout en équilibrant l'énergie résiduelle des nœuds. Des simulations ont monté qu'EOLSR offre de meilleures performances que le protocole qui minimise l'énergie consommée de bout-en-bout ainsi que le protocole qui construit les routes ayant le plus d'énergie résiduelle. SERENA, augmente la durée de vie du réseau en permettant aux nœuds de dormir. SERENA se base sur un algorithme de coloriage et un algorithme d'assignation des slots. SERENA est une solution générique capable de s'adapter aux contraintes de l'application. Les simulations ont montré que SERENA apporte un gain. Nous avons ensuite étendu SERENA pour prendre en compte les contraintes d'un environnement sans fil comme la perte des messages, l'existence des liens unidirectionnels, la mobilité... Le cross-layering est exploité pour améliorer les performances de SERENA et EOLSR en utilisant les informations fournies par la couche application et la couche MAC. EOLSR et SERENA sont implémentés dans le projet ANR OCARI centré sur les réseaux de capteurs en environnement sans fil.

Download or read book Routage Orient Optimisation nerg tique Dans Les R seaux Sans Fil written by Maher Heni and published by Omniscriptum. This book was released on 2013 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les réseaux ad hoc et de capteurs sans fil se composent de terminaux et composantes mobiles. Ce type du réseau ne repose sur aucune infrastructure établie. L'une des contraintes majeures des réseaux sans fil est l'énergie. La conservation de l'énergie est un facteur primordial pour la durée de vie du réseau. Le but de ce livre est de proposer, à travers les algorithmes de routages, des mécanismes et approches qui visent à réduire la consommation de l'énergie au sein de ces réseaux. Nous présentons, dans la première partie de ce manuscrit, une approche permettant de réduire la consommation d'énergie à travers la réduction de diffusion des messages grâce à l'interaction inter couche (concept de cross layer). Dans la deuxième partie nous présenterons un nouveau algorithme de routage permettant au noeuds composants du réseau d'échanger des données concernant les niveaux des batteries. Utilisant ces données une source sélectionne, en plus, du plus court chemin, le chemin plus sûr ( formés par des noeuds chargés).

Download or read book Mobile Wireless and Sensor Networks written by Amine Dahane and published by CRC Press. This book was released on 2019-07-01 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless networking covers a variety of topics involving many challenges. The main concern of clustering approaches for mobile wireless sensor networks (WSNs) is to prolong the battery life of the individual sensors and the network lifetime. For a successful clustering approach, the need of a powerful mechanism to safely elect a cluster head remains a challenging task in many research works that take into account the mobility of the network. In Mobile, Wireless and Sensor Networks: A Clustering Algorithm for Energy Efficiency and Safety, the authors use an approach based on computing of the weight of each node in the network as the proposed technique to deal with this problem. They present a virtual laboratory platform (VLP) of baptized mercury, allowing students and researchers to make practical work (PW) on different aspects of mobile wireless sensor networks. The authors’ choice of WSNs is motivated mainly by the use of real experiments needed in most college courses on WSNs. These usual experiments, however, require an expensive investment and many nodes in the classroom. The platform presented here aims at showing the feasibility, the flexibility, and the reduced cost using the authors’ approach. The authors demonstrate the performance of the proposed algorithms that contribute to the familiarization of the learners in the field of WSNs. The book will be a valuable resource for students in networking studies as well as for faculty and researchers in this area.

Available in PDF, EPUB and Kindle. Book excerpt: Networks are now embedded in daily life thanks to smaller, faster, inexpensive components that are more powerful and increasingly connected. Parallel to this quantitative explosion of communication networks, technology has become more complex. This development comes with challenges related to management and control, and it has become necessary to manage the service level demands of the client to which the service provider commits. Different approaches to managing one or more service level components in different emerging environments are explored, such as: the Internet of Things, the Cloud, smart grids, e-health, mesh networking, D2D (Device to Device), smart cities and even green networking. This book therefore allows for a better understanding of the important challenges and issues relating to Quality of Service (QoS) management, security and mobility in these types of environment.
