摘　　要：应用于煤矿井下环境的无线传感器网络中,不在同一通信范围内的若干节点同时发送数据时极易造成数据的冲突和延迟,影响井下监测系统的运行。通过设计一种反映节点密集度的门限值,使网络能够自主切换工作方式。仿真实验证明,改进后的方案能够降低丢包率,显著提高网络的工作效率和数据传输的成功率,并提高无线传感器网络节点传输能力。On the WSN applied in the underground the same communication range send messages at situation, when several nodes that are not in the same time, it will cause the data conflict and time delay, impact the normal operation of underground monitoring system. A threshold value of reflecting node density is designed, that can make network c independently. Simulation experiments prove that the improved scheme and improve work efficiency of network and success rate of data enhance the transmission capacity of nodes in WSN. hanging working manners can reduce packet loss, transmission, which can
