一种基于能量消耗策略的AOMDV改进协议

摘要

针对AOMDV路由协议没有考虑节点能量消耗的问题,提出一种基于能量消耗策略的AOMDV EC路由协议,旨在均衡消耗网络中每个节点的能量,达到延长整个网络生存时间的目的.通过NS2网络仿真平台对AOMDV和AOMDV EC两种路由协议的性能进行仿真实验测试,分别从网络生存时间、网络端到端的传输时延、路由开销三个维度对改进路由协议的性能进行对比分析.实验结果表明,添加能量策略的AOMDV EC协议能够有效延长网络生存时间,降低端到端的传输时延,并且有效控制了网络中的路由开销.AOMDV EC路由协议能够均衡整个网络环境中各节点的能耗,达到改善整个网络通信性能的目的.%In view of the problem that AOMDV routing protocol does not take into the energy consumption of the nodes account, an AOMDV EC routing protocol based on the strategy of energy expenditure is proposed to balance energy consumption of each node in the network and achieve the purpose of extending network survival time. And through NS2 network simulation platform,the performance of two protocol ( AOMDV and AOMDV EC) is tested,analysis of the performance of the improved routing protocol from three dimensions like the network lifetime,the end-to-end transmission delay and the routing overhead. The results show that the AOMDV EC protocol with energy strategy can effectively prolong the network lifetime,reduce the end-to-end transmission delay and control the routing over-head in the network effectively. AOMDV EC routing protocol can balance the energy consumption of each node in the network environ-ment,so as to improve the performance of the whole network communication.
