摘要
针对有向视频摄像机传感器网络的目标检测区域的覆盖服务问题,基于部署位置固定仅可连续旋转的传感器节点,增加可连续移动的轨道,提出可移动节点的传感器网络模型。基于MPSO算法,将变异思想结合系数改进的PSO算法进行改进,通过选取合适的粒子搜索策略得到改进的MPSO算法,并将其应用于求解可移动节点的传感器网络模型。在仿真实验中,通过与PSO算法、系数改进的PSO算法的比较,验证了改进的MPSO算法的有效性。一方面验证了新模型对于问题最优解更大的搜索空间,另一方面也实现了最大化覆盖区域和最小化重叠区域的目标。
For the coverage service problem of the target detection area of the directional video camera sensor network, the sensor network model of the movable nodes is proposed by adding continuously movable tracks, which is based on the sensor nodes with fixed positions and can be continuously rotated. In this paper, an improved MPSO algorithm combining with adaptive idea and variational idea is proposed and applied to solve the sensor network model of movable nodes by selecting suitable particle search strategies, which is based on MPSO algorithm. In the simulation experiments, the effectiveness of the improved MPSO algorithm is verified by comparing with the PSO algorithm and the improved PSO algorithm. For one thing, it is verified that the new model has a larger search space for the optimal solution of the problem, for another it achieves the goal of maximizing the covered area and minimizing the overlapped area.
