摘　　要：针对无线移动传感器网络的覆盖控制问题,在机会网络环境模拟器ONE的基础上进行模拟器模块的添加和修改,实现了三种覆盖控制算法,并比较了算法的性能,最后选择虚拟力覆盖控制算法进行进一步分析。通过实验研究输出采样间隔、模拟采样间隔、节点通信半径、虚拟力距离阈值等参数对覆盖控制的影响,并分析得知虚拟力距离阈值的调整可以控制传感器网络节点之间的疏密程度,进而通过减少重叠区域实现覆盖率的增加。最后进行实验分析验证了算法改进的可行性和有效性。For the coverage control problem of the wireless mobile sensor networks,the simulator module is added and modified based on the opportunistic network environment（ONE）simulator of the delay tolerant networks（DTN）environment to realize three coverage control algorithms. The performance of the algorithms is compared,and the virtual force coverage control algorithm is selected for further analysis. The influence of the parameters of output sampling interval,analog sampling interval,node communication radius and virtual force distance threshold on coverage control is studied by experiments. The fact that the adjustment of the virtual force distance threshold can control the density degree among the sensor network nodes is obtained,so the coverage rate can be increased by reducing the overlap regions. The feasibility and validity of the improved algorithm was proved by experimental analysis.
