Abstract: For wireless sensor networks nodes perform area “sleep” strategy that appears coverage “shrink” phenomenon, it combines with the network boundary effects problem, covering the border region targeted geometry division, proposes boundary region redeployment in the hybrid wireless sensor networks for nodes deployment optimization algorithms. To divide the border region some moving nodes supplement scheduling process node achieves energy balance and achieves the purpose to prolong network lifetime pass. Algorithms are compared with random deployments, random add two methods to optimize the effect of contrast, the simulation results show that this method improves network overall survival for a long time with a significant improvement for random deployment of wireless sensor network environment.
