Abstract

Wireless sensor networks (WSN) are generally randomly deployed in a given area. This initial deployment does not achieve neither area coverage, nor network connectivity. Thus, a redeployment algorithm has to be applied in order to achieve these two goals. This algorithm should meet performance criteria like saving energy and achieving stability. Our contribution in this paper is the design of DVFA, a distributed redeployment algorithm based on virtual forces. We simulate its behavior with NS2 and compare its performances with CVFA, a centralized version also based on virtual forces.
