对人工鱼群算法进行改进,改进后的人工鱼群算法与无线传感器网络中的节点分布式覆盖控制问题相结合.把无线传感器网络中节点的覆盖控制问题抽象为一个函数并利用改进后的人工鱼群算法进行寻优,提出一种新的簇头节点均匀分布调度算法.利用改进后的人工鱼群算法求得覆盖区域内节点的最优解和最优点集,使相应的节点进入休眠和工作,进行节点调度.将提出的簇头节点均匀分布调度算法和能量调度算法、簇头调度算进行仿真对比.仿真结果表明:簇头节点均匀分布调度算法可以较好的保证网络的覆盖率和减少整个网络的能量消耗.
Improvement of AFSA,combined wireless sensor networks distributed coverage control problem with improved AFSA.The coverage control problem in wireless sensor networks nodes as a function of the abstract and used the improved AFSA to optimization,Propose a new cluster head node uniformly distributed scheduling algorithm.Use the improved AFSA find an optimum solution within the coverage area of the node and the optimum set,the corresponding node goes to sleep or work,node-scheduling.The simulation analysis and comparison with the cluster head node raised uniformly distributed scheduling algorithm and energy scheduling algorithm and cluster head scheduling algorithm.Results shows that the cluster head node raised uniformly distributed scheduling algorithm have better ensure network coverage and reducing overall network energy consumption.
