摘　　要：构建基于无线传感器网络的煤矿智能监控系统能有效推进煤矿的智慧化建设,而矿井巷道无线传感器网络拓扑呈长距离带状,容易造成能耗不均、形成热区的问题。提出改进LEACH协议形成适用于矿井巷道环境下的网络路由协议:通过优化簇头阈值选取和非均匀竞争半径的簇头筛选机制控制簇头数目和位置,优化簇的划分;在簇头与sink节点进行路由选择时,将剩余能量作为节点间权值计算的重要参数,从而减少能量较小节点转发过路数据的概率,更好的均衡网络节能能耗。实验仿真结果表明,改进协议在存活节点个数和消耗总能量方面的性能优于LEACH和LEACH-C协议,有效均衡了网络能量消耗,延长了网络生命周期。The intelligent monitoring system of coal mine based on wireless sensor network can effectively promote the intelligent construction of coal mine.The wireless sensor network topology of mine roadway is long-distance belt,it is easy to cause the problem of uneven energy consumption and hot area.In this paper,an improved LEACH protocol is proposed to form a network routing protocol to be suitable for mine tunnel environment.The number and location of cluster heads are controlled by optimizing the threshold selection of cluster heads and the screening mechanism of non-uniform competition radius,and the division of clusters is optimized.When routing between cluster heads and sink nodes is selected,the remaining energy is taken as an important parameter for the calculation of weights between nodes,so as to reduce the small amount of energy.The probability of transmitting the passing data by point can better balance the energy consumption of the network.The simulation results show that the performance of the improved protocol is better than that of LEACH and LEACH-C in terms of the number of surviving nodes and the total energy consumption.
