Abstract: Maximization of network lifetime is one of the most vital objective for any Wireless Sensor Network (WSN). The proper organization of nodes become a major technique to expand the lifetime of the network. In this study, Fuzzified Clustering Algorithm (FCA) is applied for producing energy aware cluster with optimal selection of cluster heads. The FCA is performed within each node which makes it as a distributed approach. The selection criteria for the many existing cluster selection technique is generally based on the Residual Energy (RE). This study considers other parameter like Least Recently Selected (LRS), Number of Neighbours (NN) which has a major influence in network lifetime. The proposed protocol has shown 52% increase of network lifetime using static sink and 36% increase using mobile sink when comapred with few standard protocols taken for consideration. The performance evaluation of the proposed technique is compared with cluster based sensor network protocol. Extensive discussion is done for centralized and distributed sensor network.
