Abstract
According to characteristics of hydraulic support under coal mine working face, a linear-hierarchy of wireless sensor network (WSN) is proposed including its topology generation algorithm as well as how to maintain the network topology in the event of topology changes. Establishing bottom infrastructures of WSN, cluster headers will be selected to save energy design a network layout of the cluster head in the upper structure. The theory analysis and NS2 simulation results show that LHT(linear-hierarchy topology)can extend the lifetime of whole network and come to the optimal number of cluster heads under given length of deployment.
