Study on the Transmission Performance of Mine Wireless Mesh Network Based on NS2

Long distance multi-hop transmission communication is key issue to integrated video monitoring system in underground long tunnels. Wireless mesh backbone network is impossible to suit mine. However, along the long distance tunnel, multi-hop transmission performance of mine wireless mesh backbone network will be degrading. It is impossible to solve this problem. Research shows technology of multi-radio multi-channel could enhance effectively the bandwidth of the mine wireless mesh backbone network. Based on this method, this paper built the testbed of mine wireless mesh backbone network based on extended NS2, and did a series of experiment to study factors affecting the transmission performance of mine wireless mesh backbone network. At last, the solution is given.
