Research on Emergency Communication System in Coal Mine Based on WMN Technology

This paper introduced an emergency communication system based on WMN(Wireless Mesh Networks) technology.Features of some kinds of traditional communication system in coal mines were recommended.With the performance analysis between WMN and other WLAN techniques,it found that WMN is better to apply in coal mines communications system conclusively.Then,the framework and features of this communication system were demonstrated.At last,application feasibility of system was proved successfully.
