A Comprehensive Review of Cluster Based Energy Efficient Routing Protocols for Wireless Sensor Networks

In recent times wireless sensor networks have grown enormously and become progressively attractive in wide variety of applications because of their low cost, low power, small in size, self-organizing behavior in harsh environments. Routing is a vital technology in WSN. There are many routing protocols like: location based, multipath, data centric, mobility based, hierarchical routing, hybrid routing etc. Clustering is used to prolong the lifetime of the wireless sensor networks. Clustering is the process where sensing area is divided in groups to balance the energy level of sensor nodes known as clusters. An Optimal Clustering technique can reduce the energy consumption in WSN and increase the lifetime of the network. Energy is the main consideration when we analyze routing protocols for WSN. In this paper we present the study of different clustering based energy efficient routing protocols of wireless sensor networks and compared them on various parameters.
