Study to Analyze and Compare the LEACH Protocol with Three Methods to Improve it and Determine the Best Choice

摘要

The WSNs are a collection of thousandssensors or maybe more. Because of the fact that thesesensors are depending on a limited power battery, theminimizing of the power consumption is a veryimportant issue in those networks,. The LEACHprotocol has been introduced to minimize the power,but despite that it still has some defects in wasting thepower related to always choose the closest CH not thebest. In this paper we will make a detailed analysis ofthree methods to enhance the work of that protocol inthe aspects of make a best selection of the CH that thenode will attach to, and to solve the problems of the fardistances between the nodes and their CH Also, we willmake a detailed analysis and comparison betweenLEACH protocol and the introduced methods, andfinally extract the best one between them.
