In coal mine working face, there are problems such as uneven energy distribution of wireless monitoring network, the difficulty of manual maintenance and node battery replacement and energy limitation of some monitoring nodes. In order to solve the above problems, an energy optimization method of wireless monitoring network in coal mine working face based on mobile nodes is proposed by using the characteristics of periodic movement of the shearer. This method installs mobile nodes on the shearer to forward data that collected by monitoring nodes in the network to reduce multi-hop data transmission, and reduces redundant data transmission by setting transmission thresholds to reduce node energy consumption. The mobile nodes are used to radiate radio frequency energy to the monitoring nodes, which provides targeted energy supplement to the monitoring nodes so as to achieve energy balance of the network nodes. The experimental results show that compared with LEACH protocol, this method can make the wireless monitoring network energy distribution more balanced, reduce the network energy consumption and monitoring node mortality rate effectively under the same operation round, and extend the effective life of the network by 2.8 times.
