Research on the Distance-Aware WSN Routing Protocol Applied in Mine

The topology in the application of WSN (wireless sensor networks) is complex. In order to meet the need of wireless data transmission in the coal mine working environment, we propose a distance-aware routing protocol. The basis of the establishment of topology is the distance between nodes; it establishes the hierarchical relationship for each node, the data among nodes is transmitted to the sink node in the optimal path. When the structure of the network is changed, the protocol can reconstruct the routing in a short time according to the hierarchical relationship between nodes. The simulation results show that the protocol has a better convergence, and it shortens the time of local routing reconstruction. The novel protocol provides a programmer for the application of wireless sensor networks in the coal mine environment.
