Abstract:

In order to implement the self-deployment of wireless sensor networks with controllable mobility,a selfdeployment algorithm for mobile sensor networks in unknown environment is proposed.In this algorithm,the meth-ods 0f the artificial potential field and the certainty grid are adopted and the certainty is used to abstractively repre-sent the obstacles.Moreover,the network is forced by the virtual repulsive forces of the cells in the active windows to sDread itself throughout the environment. Simulated results show that the proposed algorithm is effective in the self-deDloyment 0f m0bile sensor networks,with a greatly increased coverage at the end of the deployment.
