针对配电网故障检测系统对无线传感器网络路由可靠性要求较高的问题,设计了一种面向配电网故障检测的无线传感器网络(wireless sensor network,WSN)拓扑结构,并提出了一种面向配电网故障检测的WSN可靠路由方法。其首先根据最小跳数路由方法为每一个节点分配值,之后在节点选择下一跳最优节点时考虑路径损耗以及能量损耗,并可以根据配电网故障检测业务合理调节权值来分配可靠性与能耗性的比重。仿真及实验结果表明,RRFD路由方法与传统路由方法相比,可靠性显著提高的同时有效降低了能耗,适用于配电网故障检测场景。
Aiming at the problem that the distribution network fault detection system has high requirements on the routing reliability of wireless sensor networks, a wireless sensor network (WSN) topology for distribution network fault detection is designed and a WSN Reliable Routing Method for Distribution Network Fault Detection. Firstly, it allocates the value to each node according to the minimum hop count routing method, and then considers the path loss and energy loss when the node chooses the next hop optimal node and allocates the reliability according to the reasonably adjusted weight of the distribution network fault detection service And the proportion of energy consumption. The simulation and experimental results show that compared with the traditional routing method, the RRFD routing method has significantly improved reliability and reduced energy consumption, which is suitable for the distribution network fault detection scenario.
