Energy Efficient Clustering in Wireless Sensor Networks- A Review

ANJU MALIK, Sandeep Tayal


In Wireless sensor network(WSN), it is important to reduce energy dissipation and prolong network lifetime. The data collected by each sensor is communicated through the network to a single processing center that uses all reported data to determine characteristics of the environment or detect an event. The communication or message passing process must be designed to conserve the limited energy resources of the sensors. Clustering sensors into groups, so that sensors communicate information only to cluster heads and then the cluster heads communicate the aggregated information to the processing center, may save energy. The objective of this paper is to present a state of survey on clustering parameters and also clustering algorithms reported in the literature of WSNs. Our paper also presents energy efficient clustering algorithms in WSNs.
