摘　　要：通过对AOMDV多径协议进行改进,提出了一种基于节点剩余能量策略MMBCR的多径协议(EAOMDV)。改进协议以节点剩余能量为备份路径的度量对AOMDV多径协议进行改进。使用NS2软件进行仿真,通过改变节点的暂停时间来比较EAOMDV协议和AOMDV协议的性能。仿真结果表明,与AOMDV多径协议相比,新协议路由开销和丢包率有所增加,但降低了网络的总能耗并减少了某时刻耗尽能量的节点数目,从而延长了网络的存活时间。Through improving on AOMDV muhipath routing protocol,we propose a mutipath routing protocol （EAOMDV） based on node residual energy strategy MMBCR. Node residuary energy is used for the backup path selection metric in the modified protocol. The simulation software NS2 is used, and the performances of EAOMDV and AOMDV are compared by changing the pause time of node. NS2 simulation results show that, compared with AOMDV mutipath routing protocol, the routing overhead and packet loss ratio have been increased but the total energy consumption of network has been reduced and the number of exhausted energy nodes at a moment has been decreased, so the network lifetime has been prolonged in the new protocol.
