Energy-efficient clustering for Wireless Sensor Networks-A Survey

Abstract

Research in clustering has been very active in the last two decades. Clustering schemes decreases the communication overheads, intern reducing the power consumptions and interferences among nodes. Clustering is one of the best known methods used to face this type of challenges. In this paper, we study and compare various objectives, features & characteristics of some of the popularly explored clustering algorithms & published clustering schemes in Wireless Sensor Networks like advantages and disadvantages of respective clustering schemes. This paper also presents future research topics and highlights the challenges in clustering in Wireless sensor networks.
