Maximizing mobile multimedia adhoc networks lifetime using a distributed cooperation mechanism

Energy conservation is a critical issue in wireless mul tihop ad-hoc networks, which have nodes powered by batteries only. One major metric for energy conservation is that all nodes participate in relaying requests which may be opposite to its interest but can be a solution for extending the network lifetime. We proposed a distributed algorithm which gurabtuees a cooperation between the nodes in func tion of their energy provision. We focus in this paper on the exploitation of nodes mobility. Experiments results show the impact of nodes mobility on the behavior of our proposed algorithm.
