A Coverage-Enhancing Algorithm Based on Local Virtual Force Equilibrium for Wireless Sensor Networks

摘要

To improve the coverage performance of nodes randomly deployed in a wireless sensor network, this paper proposes a local stress force-balanced method that enhances the coverage performance of mobile nodes. With this algorithm, the sensor nodes move to where the node stress virtual force by neighboring nodes in the local area (node two times the radius of perception) are in equilibrium to enhance coverage performance. A simulation experiment shows that the proposed algorithm quickly improves the coverage performance to more than 98 %. The algorithm is rapidly and efficiently deployed.
