Clustering Techniques for Wireless Sensor Networks

Wireless sensor network has been emerged as the one of the most promising area of research. The use is not limited to space research, transport, battle fields, surveillance, military, health but many more. The large number of  deployed nodes need to be efficiently organized to fulfil the need of data aggregation , load balancing and prolonging network life time  Sensor nodes are small power devices so to maintain its long life proper measure is required. Clustering serves this requirement by reducing energy consumption and increasing network scalability. In this article, we highlight the objective of clustering, discuss the different clustering approaches and its classification and finally provide a comparative study of different proposals.
