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.
