Energy Efficient Routing Protocols for Wireless Sensor Networks (WSNs) based on Clustering
Aditya Kumar, Anand Nayyar · 2014
In recent years, development of micro sensors for the purpose of tracking and monitoring has opened the door of numerous fields of sensor applications. A WSN is a collection of nodes which are organized into a network. Sensor nodes can gather the information from an unattended location and transmit to a particular user. In wireless sensor network, sensor nodes are operated with low power and small size batteries. Energy efficiency is one of the critical concerns for wireless sensor networks .There are a number of energy conservation algorithms like power scheduling algorithms, clustering algorithms and on-demand routing algorithms. Significant overhead energy consumption takes place due to tasks like processing, aggregation, message broadcasting, acknowledgement messages etc. Hence the sole purpose to design the energy conservation algorithms is that maximum energy should be consumed in transmission of sensed data to the base station and the overhead energy consumed should be minimized. Clustering is one of the robust approaches to energy-efficient sensor networking. Performance estimation of the clustering technique is the calculation of deviation from integrated optimization of different tasks like deployment, cluster formation, cluster-head selection, cluster-head rotation and data communication. The main objective of this paper is to highlight all the routing protocols which are energy efficient based on Clustering for WSN.
