چکیده
HAL is a multidisciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt età la diffusion de documents scientifiques de niveau recherche, publiés ou non, ´ emanant desétablissements d'enseignement et de recherche français oú etrangers, des laboratoires publics ou privés. La gestion efficace de la consommation de l'´ energie des réseaux de télécommunications est de nos jours un sujet d'une très grande importance. Plusieursétudes ont réussì a prouver que le routage basé sur la consommation d'´ energie réduit considérablement la consommation totale d'´ energie du réseau. Nous avons, dans cet article, combiné cette techniquè a celle de l'´ elimination de redondance de trafic, pour diminuer davantage l'´ energie consommée par un réseau coeur. Nous avons considéré une formulation robuste de ceprobì eme dans le cas o` u il existe une incertitude autant au niveau de la valeur du volume de trafic que de celui du taux de redondance. Nous proposons, pour résoudre ceprobì eme, un modèle de programmation linéaire en nombres entiers, un algorithme exact et une heuristique qui nous permettent deséconomies d'´ energie allant de 16%à 28% comparéà la méthode classique de routage basé sur l'´ energie.

Robust energy-aware routing with redundancy elimination
Many studies in literature have shown that energy-aware routing (EAR) can significantly reduce energy consumption for backbone networks. Also, as an arising concern in networking research area, the protocol-independent tra c redundancy elimination (RE) technique helps to reduce (a.k.a compress) tra c load on backbone network. Motivation from a formulation perspective, we first present an extend...
متن کاملEvolutionary Computing Assisted Wireless Sensor Network Mining for QoS-Centric and Energy-efficient Routing Protocol
The exponential rise in wireless communication demands and allied applications have revitalized academia-industries to develop more efficient routing protocols. Wireless Sensor Network (WSN) being battery operated network, it often undergoes node death-causing pre-ma...
متن کاملMinimization of Network Power Consumption with Redundancy Elimination
Recently, energy-aware routing has gained increasing popularity in the networking research community. The idea is that traffic demands are aggregated over a subset of the network links, allowing other links to be turned off to save energy. In this paper, we propose GreenRE a new energy-aware routing model with the support of the new technique of data redundancy elimination (RE). This technique,...
متن کاملEnergy Efficient Routing in Mobile Ad Hoc Networks by Using Honey Bee Mating Optimization
Mobile Ad hoc networks (MANETs) are composed of mobile stations communicating through wireless links, without any fixed backbone support. In these networks, limited power energy supply, and frequent topology changes caused by node mobility, makes their routing a challenging problem. TORA is one of the routing protocols that successfully copes with the nodes’ mobility side effects, but it do...
