Text Wireless Sensor Networks (WSNs) have emerged as an important application area resulting from the advancement of efficient short-range radio communication and miniaturization of computing devices. In a WSN, the nodes are deployed with limited battery energy and therefore enhancement of network lifetime by minimizing energy-usage is of utmost importance. One of the solutions to reduce such energy-usage is clustering of network nodes. This paper discusses the clustering approach used differently in different protocols from generic form (LEACH) to more refined form (ACM, ESDP).
