摘要: Abstract Wireless sensor networks (WSNs) are very important for monitoring underground mine safety. Sensor node deployment affects the performances of WSNs. In our study, a chain-type wireless network (CWUMSN) is first presented. A CWUMSN can monitor environment and locate miners in mines. The lowest density strategies cluster head nodes discussed theoretically. We prove that lifetime with non-uniform strategy longer than uniform strategy. Secondly, we present algorithm nodes. Next, propose dynamic choice which improve adaptability networks. Our experiments both deployments simulated. results show almost 2.5 times as long deployment. This work provides new then effectively promotes application to
