针对矿井环境特点与安全可靠性需求，在对无线传感器网络拓扑结构分析的基础上，采用Mesh网络拓扑结构，对比分析了基于接收信号强度指示（ RSSI）聚类策略和基于优先级聚类策略的两种组网方案，进行了仿真实验。结果表明：基于优先级的聚类组网方案能有效地降低移动节点组网能量消耗，减少移动节点通信时延。

Aiming at environmental characteristics and demand of safety and reliability of coal mine,on the basis of analysis on topological structure of wireless sensor networks( WSNs ),premise of mesh network topology structure,analyze comparatively the two schemes of networking between cluster strategy based on the received signal strength indication( RSSI)and cluster strategy based on priority cluster and simulation experiment is carried out. The results show that the cluster strategy based on priority can effectively reduce the networking energy consumption of mobile node and reduce the communication delay of mobile node.
