摘　　要：针对井下巷道狭长、通信环境复杂的情况,提出一种非常简单且易于执行的无线传感器网络节点部署策略—基于等腰三角形的冗余节点部署策略。它能够保证巷道至少被三重覆盖,满足了移动节点的定位要求,同时,节点的冗余部署能够在个别节点失效时仍维持数据的稳定传输。实验环境下测试结果表明:此种部署策略能够在不增加过多监测节点的同时,保证网络的低丢包率,并实现对移动节点的定位。Aiming at problem of narrow and complex communication environment in mine tunnel, a redundant node deployment strategy for wireless sensor networks （WSNs） based on isosceles triangle is proposed, which is very simple and easy to implement. It can ensure the tunnel is at least 3-covered which meets requirements of localization of mobile nodes;at the same time, the redundant deployment strategy of node can maintain stability of data transmission when individual nodes are failure. Test results show that the deployment strategy can ensure network has low packet loss, and realize localization of mobile nodes without increasing too much monitoring nodes.
