摘要
覆盖控制是延长无线传感器网络生存期一个有效的方法之一。其方法通过覆盖控制将无线传感网络节点划分成若干不相交最小覆盖连通集(CCS),然后顺序调度不同节点集。然而寻找最小覆盖连通集覆盖为NP问题,文中建立覆盖连通集优化模型,提出一种基于遗传算法(Genetic Algorithm,简称GA)目标覆盖的优化算法,并详细阐述算法实施。仿真结果显示,对于指定目标,该GA优化算法能获得比GIECC算法更好的性能。
Coverage control is the one of effective ways to extend the lifetime of wireless sensor network(WSN).By the solution above the WSN node can be taken apart into several disjointed minimum coverage connected sets(MCCS) which can be scheduled in sequence.However the problem belongs to NP.In this paper the coverage connected model has been constructed and the optimization coverage algorithm based on gene algorithm(GA) has been proposed and realized in detail.Through the simulation the performance of proposed algorithm based on gene algorithm(GA) is superior to GIECC for the intended target.
