Optimal Stable Cluster Head Selection Method for Maximal Throughput and Lifetime of Homogeneous Wireless Sensor Network

The previously reported works e.g., E-LEACH, and RCH-LEACH have proposed energy-efficient CH selection methods with coverage enhancement and varying numbers of overall CH nodes in a network. To further improve the performance, the stable CH selection method, i.e., SCH-LEACH is proposed with unexpended energy of nodes. The SCH-LEACH improves the overall lifetime of the network with minimal energy consumption. However, SCH-LEACH compromises the overall throughput of the network. The throughput analysis shows that the throughput of SCH-LEACH is lower than LEACH, E-LEACH, and RCH-LEACH. Therefore, in the proposed work, the extension of the optimal stable number of cluster head selection method is proposed, i.e., OSCH-LEACH, for reliable data transmission and a maximal lifetime of the network. The proposed work analyzes the Kopt selection for the optimal selection of CHs. The simulation results prove the superiority of the proposed protocol in terms of throughput, lifetime, FND, and LND.
