A BRIEF REVIEW ON WSN ENERGY EFFICIENT PROTOCOL

The WSN(wireless sensor network)is a collection of little energy forced devices that is called sensor nodes. The most worth for a long time of WSN is the better utilize of energy source in a sensor node. Clustering techniques are utilized to communicate with cluster-head and base station. When the CH is far off from the base station, it increases the energy consumption and decreases the lifetime of WSN.There are several cluster formation methods utilized in WSN. In which, Particle Swarm Optimization (PSO) is used to form the energy able clusters with the aid of the optimal choice of cluster head, is an able optimization algorithm. This paper presents a review on WSN for leach protocol using Optimization method.
