Performance Analysis of LEACH Protocol in Wireless Sensor Network

Sandeep Gangane | Gourav Dhawan

Abstract: Wireless sensor network are formed by small sensor nodes communicating over wireless links without using a fixed network infrastructure. A WSN is a collection of three kinds of nodes sensor node, relay node and sink node. Each node has a limited processing capability and energy sources and communication is performed via wireless medium. WSN are increasingly used in military surveillance, environmental monitoring, drug identification, education, industrial monitoring. LEACH protocol is one of the clustering routing protocols in wireless sensor networks. LEACH protocol, time is divided into many rounds, in each round. Clustering based Energy efficient LEACH (Low-Energy Adaptive Clustering Hierarchy) protocol can effectively increase WSN performance by dynamically changing cluster head. In this paper surveys working of LEACH protocol, its limitations and advancements done in LEACH to improve its performance.

Keywords: Wireless sensor network WSN, LEACH, Clustering, Clustering protocol, energy efficiency, reliability, network lifetime, etc
