Research of application of cooperative communication to underground coal mine

In view of complex electromagnetic wave propagation environment and outstanding multipath effects in coal mine, major anti-multipath methods of mine wireless communication were analyzed. According to the characteristics of cooperative communication technology, cooperative communication was proposed to apply to mine WMN communication system, and mine C-WMN communication system architecture was given. On the basis of geometry characteristics of several typical environments in mine, the corresponding modes of cooperative relay of C-WMN were analyzed.
