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 and increases net-work lifetime *** WsN is a challenging issue faced by *** systems are very helpful in detecting interfering nodes in *** have successfully applied Nature-inspired Metaheuristics Optimization Algorithms as a decision-making factor to derive an improved and effective solution for a real-time optimization *** metaheuristic Elephant Herding Optimizations(EHO)algorithm is formulated based on ele-phant herding in their *** considers two herding behaviors to solve and enhance optimization *** on Elephant Herd Optimization,a trust-based security method is built in this *** proposed routing selects routes to destination based on the trust values,thus,finding optimal secure routes for transmitting *** results have demonstrated the effectiveness of the proposed EHO based *** Average Packet Loss Rate of the proposed Trust Elephant Herd Optimization performs better by 35.42%,by 1.45%,and by 31.94%than LEACH,Elephant Herd Optimization,and Trust LEACH,respec-tively at Number of Nodes *** the proposed routing is efficient in selecting secure routes,the average packet loss rate is significantly reduced,improving the network’s *** is also observed that the lifetime of the network is enhanced with the proposed Trust Elephant Herd Optimization.
