An Optimized Novel Trust-Based Security Mechanism Using Elephant Herd Optimization

Routing strategies and security issues are the greatest challenges in Wireless Sensor Network (WSN). Cluster-based routing Low Energy adaptive Clustering Hierarchy (LEACH) decreases power consumption increases network lifetime considerably. Securing WSN is a challenging issue faced by researchers. Trust systems very helpful detecting interfering nodes WSN. Researchers have successfully applied Nature-inspired Metaheuristics Optimization Algorithms as decision-making factor to derive an improved effective solution for real-time optimization problem. The metaheuristic Elephant Herding Optimizations (EHO) algorithm formulated based on elephant herding their clans. EHO considers two behaviors solve enhance Based Herd Optimization, trust-based method built this work. proposed selects routes destination trust values, thus, finding optimal secure transmitting data. Experimental results demonstrated effectiveness of routing. Average Packet Loss Rate performs better 35.42%, 1.45%, 31.94% than LEACH, respectively at Number Nodes 3000. As efficient selecting routes, average packet loss rate significantly reduced, improving network’s performance. It also observed that enhanced with Optimization.
