Research of Deployment Strategy of Barrier Coverage for Limited Speed Mobile Target
We propose a deployment strategy to detect the mobile targets based on disk sensing model of barrier coverage and the adjustment of the distance between adjacent nodes. After analyzing the cost and the power consumption of sensor nodes, we propose a strategy by considering the critical conditions of the node radius, sensing time, and the speed of mobile target. An efficient scheduling policy between adjacent nodes is used to improve the maximum speed of detected mobile targets. The simulation results show that the proposed strategy can effectively improve the lifetime of the network.
