Mobile Ad Hoc Networks (MANET) enables mobile nodes to communicate with each other through wireless connections without any centralized controller or base station. Each mobile node is powered by a battery. The efficient use of battery energy is therefore a key factor in MANET. Optimized Link State Routing Protocol (OLSR) uses a Multipoint Relay (MPR) selection method to reduce transmitted packets during the flooding process. In the OLSR protocol, nodes are chosen as MPRs based on the WILLINGNESS and REACHIBILITY, where the willingness is related to the residual energy of the node. MPR nodes consume more energy than non-MPR nodes. As a result, we have focused on reducing energy consumption. This paper introduces a new mechanism for selecting the MPR in the OLSR protocol, in order to enhance energy management and prolong the network lifetime based on the willingness without losses of performances (such as MPRs count, The Number of Dead Nodes, end-to-end delay, control overhead, packet loss). Simulation results using Ns-3 with varying numbers of nodes show that our proposed EEM-OLSR protocol outperforms the classic OLSR by significantly improving the network lifetime.
