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 .
Highlights
WSN refers to wireless sensor nodes in which the sensor nodes work as key players to establish the wireless communication
By extensive literature review we find that two protocols LEACH and PEGASIS provides ideal paradigm for construction of highly energy efficient wireless network by increasing the lifetime of sensor nodes by optimizing the clustering process among communicating nodes
We find that PEGASIS perform better than LEACH in term of energy conservation of nodes and prolonging lifetime of network
Summary
WSN refers to wireless sensor nodes in which the sensor nodes work as key players to establish the wireless communication These nodes are geographically distributed in the network and communicate with one another and to base station to maintain the communication. By extensive literature review we find that two protocols LEACH and PEGASIS provides ideal paradigm for construction of highly energy efficient wireless network by increasing the lifetime of sensor nodes by optimizing the clustering process among communicating nodes. Both are categorizing as hierarchical Based Routing Protocols and works on data aggregation and fusion algorithms to deploy and reached sensed data from sensors to Base Station [4]. Steady phase is used for transmission of aggregated information by the cluster head (CH) to the Base station/Sink [3]
