Fuzzy based hybrid BAT and firefly algorithm for optimal path selection and security in wireless sensor network

Nodes are deployed randomly in the network area of WSN. data transmission from source to destination via intermediate nodes should be done a secure fashion. Due large size packet loss and energy consumption sensor nodes, energy-efficient path must required. The main objective this research is provide among node-to-node for efficient delivery packets destination. system uses novel hybrid firefly BAT algorithm selection, an innovative trust value generation, optimal neighborhood selection using fuzzy logic. employs Elliptic Curve Cryptography (ECC) combined with Diffie-Hellman exchange key generation exchange. Path by logic optimization has been carried out Firefly algorithms. Key includes time-based randomness factor that increases complexity cryptanalysis, thereby providing most security. performance simulation analyzed depicted terms delay, throughput, energy, processing time. simulator mobility as primary concern requires dynamic selection.
