A Novel Approach for Energy-Efficient Clustering Using NWOT-TCHE for Trust-Based Cluster Head Election in Wireless Sensor Networks

Wireless Sensor Networks must always be inexpensive and consist of tiny sensor nodes. The major challenge in WSN is energy saving by limiting the Sensor Node’s (SN) energy expenditure. Clustering is a well-known technique for conserving the energy of WSNs. It also prolongs the network lifetime of each SN in WSN. If the environment is untrustworthy, nodes in the network obviously lose their energy and spend their lifetime. A Trust-based Cluster Head Election protocol using a Novel Whale Optimization Technique (NWOT-TCHE) is presented effectively to overcome this issue. This proposed methodology mainly emphasizes the election of trustworthy SNs as Cluster Head (CH) based on five factors: the remaining energy of sensor nodes, total number of data packets accelerated by SN, average cluster distance, communication delay, and SN density. The result shows that this proposed approach is superior to the existing energy-efficient clustering approaches.
