To solve the problems undergroud coal mines on production safety
and improve the capacity of monitoring and control for mines
the undergroud multimedia sensor network(UMSN)based on MPEG-4 is proposed.UMSN’s basic function is to collect and return the video and audio imformation which multimedia sensor nodes capture in undergroud monitoring areas.The results show that in straight mine tunnels the optimal wireless communication frequency is 2.4GHz.Pull diffusion suits tunnels;Push diffusion suits places where men cannot reach.Geographical energy-aware routing is a better choice for places already known geographic imformation.
