Recent advancements in LEACH protocol in wireless Sensor Network: A review

Wireless Sensor Network is becoming popular day by day due to its growing applications in various fields. Researchers find lots of things to do in Wireless Sensor Network (WSN) due to its challenges and design issues. Due to limited battery power, WSN is constrained to extend the lifetime of network by minimizing the energy consumption. In this Clustering method is proven to be the best to reduce energy consumption and LEACH is the most popular clustering-based routing algorithm in which total energy consumed along the path for data transfer is minimized. In this paper, I have made a survey on LEACH (Low Energy Adaptive Clustering Hierarchy) and its various descendants, which help in extending the lifetime of wireless sensor network. I have also discussed the pros and cons of LEACH and a comparison is also made based on different parameters
