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。
覆蓋問題是無線傳感器網絡完成目標鑑測和信息穫取任務的前提。為瞭更貼近實際地描述區域覆蓋問題，採用概率感知模型，併把對被鑑測區域的覆蓋問題轉化為對可數箇點目標的覆蓋問題，然後利用點覆蓋算法對整箇鑑測區域的覆蓋問題進行瞭研究。最後通過倣真實驗，對網絡採用單重覆蓋與多重覆蓋的效果進行瞭比較，驗證瞭區域多重覆蓋的優越性。

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.
