| 摘 要： | AODV协议是基于最小跳数的,而没有考虑节点的剩余能量,这就容易使某些节点过早的死亡。针对这一问题,结合能量有效路由,提出了一种基于能量感知的AODV协议(AODV-EA)。新考虑了节点的剩余能量,在路由建立过程中,中间节点转发路由请求RREQ时,延迟一个与能量成反比的时间,这就最大可能地选择了路径中节点能量大的路径。仿真结果表明:改进的协议与原协议相比,推迟了节点的死亡时间,降低了丢包率。

| Abstract: | AODV protocol is based on minimum-hop,it didn't consider the node's remaining energy,so some nodes in the network are easy to die earlier.Aimed at this problem,considering the energy aware routing protocol,a kind of energy-aware-based AODV protocol(AODV-EA) is proposed.In the new protocol the node's remaining energy is considered.In the course of the routing building,when the routing request is transmitted by the middle node,a time that is inverse to the node's remaining energy must be delayed,in this way it is likely to choose a routing that is powerful.Simulation results show that compared with the old protocol,the new protocol puts off the node's death time and reduces the packet lost ratio. |
