在本文中，我们提出了一种能量有效的覆盖保持算法，称为CoCMA，它包括使用MA和唤醒方案对初始部署进行优化。CoCMA根据基于MA的节点调度关闭冗余节点，以达到节能的目的。该算法还采用唤醒机制，通过优化策略唤醒处于休眠状态的传感器节点，以保持CWSN的感知覆盖。实验结果表明，所提出的CoCMA可以成功地应用于CWSNs。与LEACH、LEACH-coverage-U、PEGASIS和EGDG相比，该算法最大限度地减少了CWSN运行期间的活动节点数，从而更好地保持了感知覆盖。此外，如果选择合适的节点位置和汇聚节点位置，CoCMA的性能将得到显著提高。本文给出了一些有希望的结果
In this paper we have proposed an energy-efficient coverage-preserving algorithm, called CoCMA, which encompasses optimization for initial deployments using a MA and a wake-up scheme. The CoCMA turns off the redundant nodes according to the MA-based schedule for nodes in order to save energy. It also used the wake-up scheme to awaken some sensor nodes in a sleeping mode through an optimization strategy to preserve the sensing coverage of the CWSN. The experimental results show that the proposed CoCMA can be successfully applied to the CWSNs. It minimizes the number of active nodes during the operation period of the CWSN, so the sensing coverage is better preserved comparing with the LEACH, LEACH-Coverage-U, PEGASIS and EGDG. Moreover, the performance of the CoCMA could be significantly improved if the positions of the sink are chosen and the nodes are chosen appropriately. With the promising results demonstrated in this paper
