摘　　要：无线传感器网络应用场合拓扑结构复杂,针对煤矿井下工作环境中的无线传输数据需求,提出了基于距离有效性的层次路由协议。协议以节点间的距离为建立路由的依据,作为各个节点建立层次关系,节点间的数据以最优路径向汇聚节点传输。当网络结构发生变化时,协议可按照节点间的层次关系在较短时间内重建路由。仿真结果表明,协议具有较好的收敛性,并缩短了重建局部路由的时间,为无线传感器网络应用于矿井环境提供了一种方案。The application of WSN was complex. In order to meet the view of coal mine working environment in the wireless data needs, This paper put forward the routing protocol based on the distance to the level of effectiveness. The distance between nodes which was the basis for the protocol established level relations between the node data convergence to the optimal path to the node transmission. When the structure of the network was changed, the protocol could reconstruction routing in short time between the node level relations. Simulation results show that the protocol is convergence, and the reconstruction of local routing time is shorter. WSN supplied a way to the application of mine.
