A Survey on Energy Optimization in WSN using Distributed Clustering Approach

Swati Dewangan, S. D. Mishra

Recent advancement in technologies serving various smart applications has led to the expansion of wireless networks consisting of sensor equipped devices. The sensing devices in Wireless Sensor Networks (WSN) are randomly deployed across the large environmental regions to monitor the real-time occurrence of events. The sensor nodes coordinate and communicate the acquired data with other distant nodes upon sensing and assessment operations. Most of the energy of sensor nodes gets depleted in the data communication process. To reduce the overall energy consumption in the WSN clustering is widely used as an optimal approach.This paper presents a survey on recently adopted distributed clustering mechanisms for balancing the energy consumption and enhancing the lifespan of the WSN. The benefits and issues of each identified approaches are also emphasized.
