基于概率感知模型的集中式区域覆盖算法研究

摘要

覆盖问题是无线传感器网络完成目标监测和信息获取任务的前提。为了更贴近实际地描述区域覆盖问题，采用概率感知模型，并把对被监测区域的覆盖问题转化为对可数个点目标的覆盖问题，然后利用点覆盖算法对整个监测区域的覆盖问题进行了研究。最后通过仿真实验，对网络采用单重覆盖与多重覆盖的效果进行了比较，验证了区域多重覆盖的优越性。%Region coverage is a basic premise to realize target monitoring and information acquisition in wireless sensor net⁃work. In order to describe the region coverage more closely to the actuality,the probabilistic sensing model is applied,and the coverage of the monitored area is turned to the coverage of the countable point targets. The coverage of the whole monitored area is investigated by means of the point target coverage algorithm. The effects of single coverage algorithm and multiple coverage al⁃gorithm are compared by means of simulation experiment. The superiority of multiple coverage algorithm was verified.
