Wireless Multi-hop Self-Organizing Network in Tunnels

The communications in tunnels is always a severe problem for its special environment. The multi-hop wireless self-organizing network, which uses many wireless points (WPs) to relay the signal as a virtual Base Station(BS), with characteristics of lower power, self-organizability can be the most appropriate solution to it. This paper analyzes system power efficiency of this multi-hop network and numerical simulation is conducted to evaluate the effects. Finally the conclusion is drew that with the increasing of the numbers of WPs and the maximum number of allowable hops, the required system power will be reduced obviously.
