A wireless sensor network is used as an effective tool for gathering data in various situations. Recent researches in wireless communications and electronics has enforced the development of low-cost wireless sensor network. Wireless sensor networks are web of sensor nodes with a set of processors and limited memory unit embedded in it. Reliable routing of packets from sensor nodes to its base station is the most important function for these networks. The conventional routing protocols cannot be applied here due to its battery powered nodes. To support energy efficiency, nodes are often clustered in to non-overlapping clusters. This paper gives a brief overview on clustering process in wireless sensor networks. A research on the well evaluated distributed clustering algorithm Low Energy Adaptive Clustering Hierarchy (LEACH) and its followers are portrayed artistically. To overcome the drawbacks of these existing algorithms a distributed clustering model has been proposed for attaining energy efficiency to a larger scale.
