Jianchao Zeng · Computer Technology and Development · 2009
The deployment of the nodes is of importance in WSN,it reflects the cost and the capability of monitoring.In order to reduce the coverage holes and improve the coverage rate in wireless sensor networks,a new algorithm for optimizing the deployment of mobile nodes is presented,which is based on the particle swarm optimization(PSO) model.The PSO is used to optimize the position of mobile nodes,the deployment of the nodes can be obtained by the optimal solution.Results of simulation show that the algorithm can reduce the coverage holes utmostly,and improve the coverage rate efficiently.
