Abstract

Abstract

To capture sensed data from different locations, Wireless sensor network (WSN) requires large number of sensors in the monitoring area. A sensor helps in sensing and forwarding data to an application data store but due to inadequate energy, preserving the network lifetime and its operation remains a major challenge in WSN. To overcome this challenge different clustering techniques are proposed in literature. LEACH is a primitive clustering technique from which most of the latest clustering techniques stem in. Many recent studies have focused on the optimization of cluster based WSNs through fine tuning of LEACH parameters and other related parameters. Motivated by this, we reviewed the latest optimized variants of LEACH in this paper. This survey will provide a roadmap for future researchers to scrutinize LEACH and its variants in terms of optimization technique used and parameters used for clustering.
