LEACH based Clustering Technique in Wireless Sensor Network

Abstract

Wireless Sensor Network (WSN) consisting of an hundred or thousand number of nodes which are deployed manually or randomly in the target region, and is useful for environment monitoring & tracking purposes. These nodes sense the environment's information, change into an acceptable form of signal, thereafter send it to the respective destination. Energy saving is the prime aim in WSN, which depends upon the clustering and packet routing. We studied various clustering protocols that were based on LEACH. We have found that dynamic Cluster Head (CH) selection process is necessary in WSN. In Low Energy Adaptive Clustering Hierarchical (LEACH), the CH selection was random, and didn't include energy aware parameters. In this paper, we give the comparison of LEACH based clustering protocols. We have also found that Three Layer LEACH (TL-LEACH) gives the better results as compare to other clustering algorithms like LEACH and E-LEACH. TL-LEACH is also useful for saving the node's energy in large geographical area and increase the lifetime of the WSN.
