摘　　要：提出了一种基于AODV的节能路由算法EBF-AODV.该算法在路由发现过程中,源节点设置一个阈值,中间节点根据本节点拓扑变化情况决定如何处理路由请求分组,目的节点综合考虑路径上的可用能量和路由跳数,选择最佳路径.通过仿真证明了该算法的有效性.This paper proposed an energy saving routing arithmetic called EBF-AODV which based on AODV.During the route discovering,the source node will provide a threshold.Each node determines how to deal with RREQ based on its topology change ratio.At the destination,RREP is only generated for the RREQ with minimum routing cost..The simulation experiments confirmed that validity of EBF-AODV.
