Abstract: In Ad hoc networks,routing protocols just like AODV don’t take the energy of nodes into account during routing discovery process,which may cause network partition on account of energy drain of some nodes.This paper proposes an energy saving routing protocol named ECAODV based on AODV.During routing discovery,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 with current protocols.

Key words: Ad hoc, residual energy, network partition, neighbor set, stability of network

摘要: 在Ad hoc网络中,AODV等路由协议在选择路由路径时没有考虑节点的能量,可能造成部分节点的能量过度使用从而导致网络分割等问题。以AODV为基础,提出了一种基于节点剩余能量和网络稳定性的路由算法ECAODV。该算法在路由发现过程中,不仅要综合考虑路径上的节点的剩余能量和路由跳数,而且考虑路径中间节点对网络稳定性的影响。通过仿真验证该算法有较好的性能。
