摘　　要：根据井下巷道的实际工作环境,提出了一种适用于井下巷道的无线传感器网络路由算法。算法根据接收节点的位置和剩余能量来确定最优转发节点,既减少了多跳路由传递的时间又均衡了节点能耗;算法在路由过程中节点失效时利用路由切换技术,通过对侧的节点形成互补路由来继续路由过程,大大增加路由的可靠性。仿真实验及分析表明,与其他典型的井下巷道分区算法相比,该算法生成的路由有更短的时延和更高的数据传递率,适合于井下巷道环境。A routing algorithm of Wireless Sensor Network（WSN）is proposed for roadway in coal mines according to its working environment. Firstly, the algorithm determines the optimal forwarding node based on the location and remaining energy of the node, which shortens the time to deliver the message in the multi-hop route and balances the node energy consumption. When nodes fail in the routing process, the algorithm, using routing switching technology, generates complementary route to continue the routing procedure through the opposite side of the node, greatly increases the reliability of routing. Simulation and analysis show that, compared with other typical partitioning algorithm for the roadway, the route generated from the algorithm has a shorter latency and a higher data transfer rate and is more suitable for the coal mines environment.
