Energy efficient routing of WSN using particle swarm optimization and V-LEACH protocol

In this paper, cluster head and vice cluster head selection is discussed and a method of energy efficient routing is presented based on both particle swarm optimisation technique and V-LEACH protocol. Performance comparison with existing leach protocol shows proposed protocol provides better performance to minimize energy dissipation in the transmission and increases the life time of the wireless sensor networks, also other comparative performance metrics like End to End delay, data transmitted and total energy consumed shows proposed protocol provides better performance in comparison to existing leach protocol.
