Power saving route algorithm on underground Wireless Sensor Networks

The routing protocol which can meet the requirement of underground wireless sensor network had a decisive role on the monitoring quality and the survival time of network. By combining the beacon nodes chain deployment of tunnel Wireless Sensor Networks, the Minimum Energy Relay Routing (DMERR) algorithm which is based on dynamic path loss parameter is proposed, this algorithm can save the energy of communication by obtain the exact path loss parameter of each place in roadways and calculation the optimum communication distance accurately. The simulation results show that this routing algorithm can meet the requirements of the underground linear wireless sensor networks and reduce the routing energy consumption effectively.
