在考虑路由稳定性和能量感知路由协议的基础上,提出一种方案,简称RESA-RM。定期间隔检测信号强度、剩余能量及接口队列长度;通过跨层法实现对路由的维护,依据“先接后断”路由修复机制主动地为数据传输建立替代路由;通过在NS2上的实验模拟对比该协议与其它类似路由协议如RSEA及LAER。实验结果表明,该方案在数据包传输率、开销控制和端到端时延方面表现了很好的性能。
A scheme RESA-RM was proposed to enhance the route maintenance process in route stability and energy aware rou-ting (RSEA)protocol through cross layer approach.Firstly,the signal strength,residual energy and interface queue length were monitored.Secondly,the cross-layer method was implemented to maintain routes,and the alternate route for data transfer through“make-before-break”route repair mechanism was established.At last,this protocol was compared with other similar routing protocols including RSEA and LAER on NS2 under different mobility conditions.Experimental results show the pro-posed scheme has better performance in terms of control overhead,packet delivery ratio and end-end delay.
