摘　　要：为建立满足配电网通信Qo S需求的路由机制,建立合理的配电通信网WMSNs结构方式,对配电通信网业务需求进行了分析,提出一种保障Qo S面向配电通信网的WMSNs多路径路由算法(MRFD)。根据多步前向区域建立多路径树,使用距离、角度的综合条件来反向选取下一跳,并进行精简,建立了多路径。在传输路径的选取时,使用结合节点个数、单包传输能耗、剩余能量的多因素路径函数。实验表明MRFD满足配电网通信的Qo S需求,并有效优化延迟、延长生命周期,实现了能量的均衡使用。To meet the QoS demand of distribution network communications and establish a reasonable distribution network structure in WMSNs way, after analyzing the distribution network business requirements, this paper proposed a QoS assured muhipath routing for distribution communication network （MRFD）. It used multistep forward area to build multi-path routing tree. Factor combines distance and angle was the principle to select next node in reverse direction, and then simplified the path. Factor combines routing energy consumption, total energy and hops was the principle to select the path. Simulation re- sult indicates that MRFD not only satisfies the QoS requirements of distribution network, but also effectively optimize delay, lengthen lifetime and balance the energy.
