Energy Conservation for Ad Hoc On-Demand Distance Vector Multipath Routing Protocol

Routing in ad hoc mobile networks is a problem which has not yet been satisfactorily solved. Traditional routing techniques are not well adapted to new networks. Indeed, their lack of reactivity with respect to the traffic and network changes means traditional routing techniques cannot easily be used except at the price of over-dimensioning of the network resources (network bandwidth, node memory utilization, node CPU load, etc.). In recent years the research community has been interested in the improvement of ad hoc routing, and among the solutions suggested multipath routing has been considered. Multiple paths are exploited in order to ensure reliability and a quick reaction to changes in topology with a low overhead generated by the control messages. In this article we present an extension of the well-known routing protocol AODVM (Ad hoc On-demand Distance Vector Multipath). We propose to improve the multipath routing strategy with a path classification to allow the paths with the best energy level to be chosen.
