摘要
针对输电线路监测系统对于无线传感器网络路由部署可靠性要求高的问题,分析了输电线路监测系统中的无线传感器网络拓扑结构,提出了一种面向输电线路监测的无线传感器网络可靠路由方法。方法首先根据输电线路监测系统中上层网络的通信质量以及双向链路的链路质量,为节点选择数据上传的Sink节点;然后通过综合考虑节点可靠性、节点剩余能量和邻节点跳数3个因素,实现路由路径的最优下一跳节点选择。仿真实验结果表明,所提方法与长链状蚁群路由算法以及传统LEACH算法相比,在降低节点能耗前提下能够降低丢包率,适应于输电线路监测系统应用场景。
In power transmission line monitoring system, wireless sensor network （WSN） requires routing implementation with high reliability. Based on analysis of the system＇s WSN topology, this paper proposed a reliable WSN routing method for power transmission line monitoring system. Firstly, a sink node was selected for each node to determine data transmission direction, considering two factors： communication quality of upper layer network and WSN link quality. Then, optimal routing path was established by next-hop node selection, fully considering three factors： WSN-node reliability, WSN-node residual energy and neighbor-node hop. Compared with long-chain ant-routing method and traditional LEACH algorithm, simulation results illustrate that the proposed method performs less packet loss rate with premise of lower WSN-node energy consumption, suitable for application in power transmission line monitoring system.
