Enhanced AODV routing protocol based on energy efficient

The traditional AODV protocol uses an algorithm of basic route discovery to set up a route path between the source node and the destination node regardless of residual energy of the nodes.The article proposes an enhanced AODV routing protocol.It applies an algorithm,which considers residual energy of the nodes during the course of setting up the route path,to confirm the forwarding delay of the RREQ packet and to set up a route path by selecting the noses which have more residual energy.The simulation results show that,compared with AODV,EM-AODV enhances the energy efficient and lengthens the network lifetime.
