To Enhance the Lifetime of WSN Network using PSO

K.SyedAliFathima, T.Sumitha

The major issues in wireless sensor networks is to maximize the network lifetime of sensors.The best energy efficient protocol is LEACH to reduce the energy consumption and it can extend the lifetime of wireless sensor network.Clustering techniques can be used to communicate with cluster-head and base station. If the base station is far away from the cluster-head ,energy consumption will be increased and it can reduce the lifetime of wireless sensor network.To overcome these, Paticle swarm Optimization technique is implemented with this protocol inorder to achieve maximum lifetime of wireless sensor network.PSO is used to extend the scalable and energy efficiency. It is easy to implement and the mutation calculation speed is very fast
