Energy Efficient Routing Protocol Based on Energy of Node and Stability of Topology

In Ad hoc networks, common routing protocols didn’t take the energy of nodes into account during routing discovery process, which may cause network partition on account of energy drain of some of nodes. This paper proposed an energy saving routing protocol named ECAODV based on AODV. During routing discovering, the source node not only takes the residual energy of the intermediate nodes and hops, but also considers the influence of motivation of those nodes imposed on the topology of network. Simulation results show that the proposed protocol achieves better network service performance compared to current protocols.
