k-coverage strategy of wireless sensor networks
无线传感器网络k重覆盖优化策略

To maximize the network k-coverage and extend the life of the network, this paper proposed a k-coverage strategy of WSN based on PSO. It improved the k-coverage rate and the use ratio of need, and thus prolonged the network lifetime. To the premise of ensure network coverage accuracy, it chose the most suitable parameters, both to ensure optimal coverage of the results and to maximize the computational savings, extend the life of the network. The paper analyzed the influence about relevant parameters of particle swarm optimizer on the coverage performance through the simulation experiment. Experimental results indicate that the k-coverage strategy of WSN acts effectively in k-coverage optimization.
