SURVEY ON CLUSTERING ENERGY EFFICIENT IN WIRELESS SENSOR NETWORKS.

A Wireless Sensor Network is a consisting of spatially distributed autonomous systems with a communication for monitoring and recording conditions at diverse locations. WSN is built of nodes from a few to several hundred or even thousand, where each node is connected to one sensors. WSN is an emerging and attractive research area in which several applications such as health care, smart home, agriculture, and military are making use of it. Energy efficiency is one of the most important issues in wireless sensor network. A cluster is a group of servers and other machines act like a single system. Clusters enable high availability, load balancing and parallel processing in certain situation. Clustering algorithm is used to reduce the energy consumption and improves the lifetime of the network. Clustering reduces traffic flow, minimizes energy consumption, increase residual energy and extend the lifetime of the sensor network. This paper includes study of various energy efficient clustering algorithms in Wireless Sensor Networks. [ABSTRACT FROM AUTHOR]
