  • 摘要: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.COTSis an improvement of LEACH is used by removing the cluster-reforming process and adding a rescheduling slot to the end of every round, energy is significantly saved.A novel routing protocol adapting Minimum Spanning Tree (MST), is formed using Prims algorithm to maximize network life time and reduce network delay. The results were analyzed based on the overall improvement and performance of the network.
