In order to optimize the deployment performance of sensor nodes,the present research proposed a sensor deployment strategy,so-called virtual force based multiple particle swarm optimization(VFMPSO).VFMPSO combines the virtual force(VF) algorithm on the basis of the evolution of multiple particle swarm optimization(MPSO).The strategy uses the virtual force to direct the updating of MPSO for improving the convergence speed.By using the method of multiple group parallel searching,it avoids a phenomenon of premature and improves the network coverage rate to the largest extent.Simulation results show that VFMPSO has advantages over VF and MPSO in terms of coverage,iteration number and deployment time.
