Covering the surveillance region is a key task for wireless sensor networks. For mobile sensors, the deployment of sensors at\nappropriate locations is the key issue for sufficient coverage of surveillance area, and efficient resource management of sensor\nnetwork. Previous studies most utilize physical coverage model for developing deployment schemes, in that the sensor resources\nmay be wasted during the deployment for coverage. In this paper, a novel movement-efficient deployment scheme for mobile sensor\nnetworks is proposed, which adapts the information coverage model and the classical potential field method. The performances of\nthe proposed scheme are evaluated comparing to two other schemes in aspects of coverage rate, coverage hole rate, ideal moving\ndistance, and actual moving distance through extensive simulations. Simulation results show that the proposed scheme performs\nbetter than these related schemes in both coverage and movement efficiency.
