Efficient Cluster Formation Protocol in WSN

Abstract

WSN which is called as Wireless Sensor Networks plays vital role in many applications. Most WSNs exploit clustering method for data communication from sensor destination nodes to the sink. So, Clustering should be made as efficient as possible. In most of the existing clustering protocols, residual nodes (non-cluster nodes) may be formed during clustering. Though these nodes can send their data directly to the base station, it needs large amount of energy. In the proposed method, PSO algorithm which is termed as Particle Swarm Optimization is used for cluster configuration which evades the formation of residual nodes. The base station performs cluster formation. Network Simulator-2 (NS-2) tool is used to achieve simulation. Simulation outcomes reveal enhanced operation of the proposed protocol than existing LEACH and OEERP protocols.
