A Movement Control Strategy Based on Node Coverage in Multi-tier Mobile Sensor Network

Q. Li, H. Guo, M. Yu

Abstract:	The mobile Wireless Sensor Network (WSN) has been a new research focus for its applications of special environment. Based on multi-tier mobile WSN, a novel movement control strategy of fusion nodes is proposed in this paper. Different from the previous movement control strategy, which divided the surveillance area into several subareas and deployed mobile fusion nodes to implement partition control, our strategy focus on global network topology. We try to avoid some defects caused by area partition and aim to cover sensor nodes with fusion nodes. The strategy first divides all sensor nodes into a number of communication sets so that mobile fusion nodes can collect data by traversing those sets. Then combine Virtual Attractive Force (VAF) model with Local Closest First (LCF) algorithm to design fusion nodes’ optimal mobile route for data collection. Simulation results shown that the strategy can ensure the efficiency and reliability of network data collection.
