In this article, we propose a protocol to cluster a WSN through taking advantage of the shortcomings of known protocols (i.e., LEACH, T-LEACH, and MT-CHR), namely, Centralized Density- and Threshold-based Cluster Head Replacement (C-DTB-CHR) protocol that mainly aims at optimizing energy through minimizing the number of re-clustering operations, precluding cluster heads nodes premature death, deactivating some nodes located at dense areas from cluster's participation, as well as reducing long-distance communications. Interestingly, our simulation results show impressive improvements over what are closely related in the literature in relation to the network lifetime.
