针对具有单一移动采集节点的无线传感网,考虑数据采集的相关因素对移动采集节点路径规划的影响,建立了基于移动采集节点单位时间内采集的数据总量最大化的数据采集路径规划数学模型,并设计了模拟退火算法对该问题进行了求解。实验仿真证明,文中设计的数据采集策略可以大大地提高移动采集节点的数据采集效率,最大化地发挥移动采集节点的功能,减小无线传感网络中静态传感器节点的通信负载,优化网络生存时间。

Considering the influence of the related factors in data collecting on mobile nodes routing, a mathematical model is constructed for mobile nodes routing in wireless sensor networks with a single mobile node, based on maximizing the amount of data collected per unit time. The simulated annealing algorithm is used to solve the problem, and the simulation results shows that the efficiency of mobile date collector is improved greatly by the data collecting strategy designed in this paper, and the function of mobile date collector is maximized.
