Performance Analysis of Virtual Force Models in Node Deployment Algorithm of WSN

Node deployment is an essential and important issue in WSN for it not only determines the energy cost and communication delays for sensors network, but also affects how efficient and maximum a region is covered and monitored by sensors. Virtual force models receive more interests in coverage algorithms of node deployment of WSN. In this paper we analyze the parameters of four virtual force models, and then choose four evaluation factors, which are coverage increment scale, iterative number, coverage efficiency and average movement distance of nodes, to evaluate these virtual force models. We proved that virtual force model of three parameters was a better one, as well as force model which don't considering its force value but direction.
