The Research and Design of High Reliability Routing Protocol of Wireless Sensor Network in Coal Mine

Wireless sensor network (WSN) is a novel technology in acquiring and processing information and has been an active research area in recent years. In this paper, firstly, a high reliability routing protocol is designed which is able to rapidly detect the change of topological and routing information of network, choose the best route, recover route when some nodes damaged. Secondly, the basic information table created for each node which makes routing recovery simple and easy to be realized. Finally, to evaluate the routing protocol scalability and reliability, a large-scale simulation based on the data collected from the prototype experiment conducted.
