The Ad hoc network is an energy-limited system with its nodes powered by batteries.The most important merit when evaluating a given protocol is its ability to decrease node energy consumption and prolong network service life.Typical routing protocols presented by the MANET group of IETF are based on least hops,without consideration of energy consumptions.To solve this problem,an improved routing protocol based on Ad-hoc on-demand distance vector(AODV) is presented for a mobile Ad hoc network.It is a protocol of energy efficient and load balanced,in which the jitter delay of a node is determined by its current energy level and load.Thereby,the nodes with more residual energy and less load can enter the route more quickly,energy consumption in the network can be fairer,and node loads can be more uniform,so that the data flow can not be clogged in some section.Simulation results showed that,compared with basic AODV protocol, the proposed protocol decreases end-to-end delay,improves the network throughput rate,prolong the service life of whole network and raises the network performance.
