Performance Comparision of LEACH, SEP and DEEC Protocol in Wireless Sensor Network

Abstract

Wireless Sensor Network is the network of power-limited sensing devices called sensors. Wireless sensor network is differ from other networks in terms of optimization of amount of energy because when these sensors sense and transmit data to other sensors present in the network, considerable amount of energy is dissipated. Various routing algorithms are proposed to limit the powers used by the wireless sensors. Hierarchical routing protocols with the concept of clustering like LEACH and SEP and DEEC are already best known for maintaining energy efficiency. In this paper, we will compare these three protocols in terms of packet transmission, energy dissipation and number of nodes alive and stability period and we will discuss the advantage and disadvantage of these protocols under various conditions.
