JWCN_V5_N2_RP2 Harjeet Kaur Beant Kaur Journal On Wireless Communication Networks 2320 - 2351 5 2 10 16 WSN (Wireless Sensor Network), LEACH (Low Energy Adaptive Clustering Hierarchy), MTE (Minimum Transmission Energy), SCH (Super Cluster Head), MCH (Mini Cluster Head) Wireless Sensor Network is one of the vast areas of research for scholars. In this, energy consumption is a major problem and various protocols are applied till date to reduce it. The main purpose of this paper is to study some of the protocols such as direct transmission, MTE and LEACH. Nowadays, LEACH is a focused area to gain better results. So much research has already been done in this field, but still a lot more can be done to improve the overall performance. After analyzing all these, the authors have tried to decrease the power consumption of WSN using LEACH protocol. The experimental results show that there is an improvement in all parameter terms and more rounds have been energized when compared to basic LEACH. Simulation of the improved LEACH has been carried out on MATLAB and results have been verified and compared with parameters such as dead nodes, alive nodes, sending packets to Cluster Head or base station, etc. July - September 2016 Copyright © 2016 i-manager publications.
