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
