基于快速检测和恢复的无线传感器网络路由协议研究

Research into a Fast Detection and Recovery Routing Protocol for WSN

随着无线传感器的广泛应用,路由协议的容错性已经成为研究的热点,针对DD协议容错的缺点,本文提出一种主路径节点故障快速检测和恢复的无线路由协议,根据不同情况灵活采用自身检测和后节点检测方法,达到迅速检测节点故障的效果。实验仿真结果表明,相同节点数量的情况下,同定向扩散协议相比,明显降低了无线传感器网络的数据丢失率和故障恢复时间,提高了网络的可靠性。

The wide use of wireless sensors has made fault tolerance of,routing protocol a hot research issue.In view of the features of high fault and the low recovery speed in wireless sensor network＇s node,this paper proposes a wireless routing protocol which can rapidly detect the fault node and recover the main path.It can adopt self-detection and back node detection according to different conditions,to achieve rapid detection effect of node fault.Simulation results show that,given the same number of nodes,data loss rate and fault recovery time of wireless sensor network decrease obviously compared with DD protocol,so the reliability of WSN is improved.
