覆盖保存是WSN的一个基本质量要求。选择一个最佳的簇头，以满足长时间的监视区域的完全覆盖。使用覆盖意识的方法来选择簇头，而不是基于能量的方法，可以增加场景有效时间。(WSN coverage preservation is a basic quality requirements. Choose one of the best cluster head in order to meet long surveillance area completely covered. Awareness of the methods used to select the cover cluster head, rather than energy-based method, can increase the effective time of the scene.)
