Research on Wireless Sensor Network Optimization in the Platform of Coal Mine Safety Monitoring

The traditional wireless sensor network for coal mine need to improve in view of the complexity of underground production and poor communication environment.This paper focuses on the optimization design of network communication protocol,routing protocol and RSSI localization algorithm of underground wireless sensor network,and the improved effect is verified by simulation experiment.The results show that the improved wireless sensor network can save the energy of network nodes and improve the locating accuracy of downhole nodes,so it has strong applicability.
