Abstract

Energy Efficiency is the most crucial requirement of sensor nodes in WSN networks. Sensor nodes are the communicating nodes of wireless network which lost their energies with package of time due to having small battery life. So, for sustaining the wireless network to work for longer period of time there requires the need of energy efficient routing protocols [1]. Here in this paper we are presenting LEACH (Low Energy Adaptive Clustering Hierarchy) and PEGASIS (Power Efficient Gathering in Sensor Information System) protocols [2] as most energy efficient protocols to prolong the higher lifetime and small delay time of WSN network.
