Research on the Fast Network Rollout Performance of Mine Multimedia Emergency Communication System based on WMN

摘要

A Multimedia Emergency Communication System based on Wireless Mesh Network in Coal Mine(MECS-WMN) is proposed. Audio, video, environmental data (methane, oxygen, temperature, carbon monoxide, hydrogen sulfide) and rescue personnel position information of Disaster Site, which captured by mining multimedia Terminals are transmitted through the Wireless Mesh Network to Mine Rescue Base and Ground Rescue Center in real-time. The program of using current wireless AP signal strength determines the next AP laying location to solve the problem "Fast Network Rollout, Plug and Play" of MECS-WMN. The experiment results show that the program truly implements real-time communications between rescue workers and command bases, which plays an important role in emergency communication and mine safety.
