基于Dynamic POIs的Sweep Coverage节点移动算法

为了解决以往研究Sweep Coverage机制中POIs总是事先确定的、静态的、其位置、间隔时间等信息固定不变的,缺乏灵活性的问题,提出了一种名为DDSweep的基于信息素浓度的Sweep Coverag机制.当有新的POI出现,有旧的POI消失,即POIs是事件驱动的、动态的,存在POI的移入移除时.在没有一个集中式控制的情况下,该机制能让移动节点及时到POI处采集数据.仿真结果表明,DDSweep机制较以往的Sweep Coverage机制更能适应实际的Dynamic POIs环境需要.

Controlling the mobility of sensors in Sweep Coverage based on Dynamic POIs

To address the mechanism of previous studies Sweep Coverage POIs always predetermined, static, and its location, and time interval information fixed, inflexible problem, proposed a mechanism called DDSweep based on the concentration of pheromone Sweep Coverage.When a new POI appear, disappear with the old POI that POIs are event driven, dynamic, there is removed into the POI. In the absence of a centralized control case, the mechanism allows the mobile node at the time to collect their data.Simulation results show that, DDSweep mechanism is more adapted to Dynamic POIs real environmental than the previous Sweep Coverage mechanisms.
