Reliable routing protocol of wireless sensor networks for roadway in coal mines
HU Changju · Computer Engineering and Applications Journal · 2013
A routing algorithm of Wireless Sensor Network(WSN)is proposed for roadway in coal mines according to its working environment. Firstly, the algorithm determines the optimal forwarding node based on the location and remaining energy of the node, which shortens the time to deliver the message in the multi-hop route and balances the node energy consumption. When nodes fail in the routing process, the algorithm, using routing switching technology, generates complementary route to continue the routing procedure through the opposite side of the node, greatly increases the reliability of routing. Simulation and analysis show that, compared with other typical partitioning algorithm for the roadway, the route generated from the algorithm has a shorter latency and a higher data transfer rate and is more suitable for the coal mines environment.
