A Van der Waals Force-Like Node Deployment Algorithm for Wireless Sensor Network

Abstract

The effectiveness of wireless sensor networks(WSN) depends on the coverage and connectivity provided by node deployment, which is one of the key topics in WSN. In this paper, a virtual force-based self-deployment algorithm for nodes with mobility using a force model similar to van der Waals force is proposed. In the proposed approach, all nodes are seen as points subject to repulsive and attractive force exerted among them, nodes can move according to the calculated force. Simulation results and comparisons have showed that the proposed approach has higher coverage rate, faster convergence time and less energy consuming than traditional virtual force algorithm.
