Performance Evolution of LEACH, COTS and MST Algorithms in Cluster Formation with Cluster Head Selection in Wireless Sensor Networks

The distributed mechanism of LEACH algorithm is used for cluster formation and cluster head selection, it may result in poor cluster structure in which some clusters contain a much larger number of nodes than others do. Furthermore, randomly choosing CHs lead to the fact that there is a high chance for one node to be a CH during several rounds of operation, this node consumes more energy and may die out within a short period of time. Clustering with One-Time Setup (COTS) is an improvement of Low-Energy Adaptive Clustering Hierarchy (LEACH) is used by removing the cluster-reforming process and adding a rescheduling slot to the end of every round energy is significantly saved.
