An Energy Optimization Algorithm for Mobile Ad Hoc Network

Optimized Link-State Routing (OLSR) protocol presents the advantage of finding a route between two nodes in the network in a very short time, thanks to its proactive scheme, but it can expend a lot of resources selecting the MultiPoint Relays (MPR) and exchanging Topology Control information. We present in this paper a new mechanism for OLSR, aiming to improve energy management in mobile ad hoc network; we are describing a modification in the MPR selection based on the willingness concept, by introducing residual energy of node. It is concluded that this solution decreases significantly the number of dead nodes by always choosing stable nodes with important residual energies as MPRs, which prolong the lifetime and enhance the performance of a mobile ad hoc network.
