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

In recent times wireless sensor networks have grown extremely and become increasingly striking in big variety of applications due to their low cost, low power, small in size, self-organizing behavior in unsympathetic environments. Routing is a vital technology in WSN. There are many routing protocols like: Location-based Protocols, Data Centric Protocols, Hierarchical Protocols, Mobility-based Protocols, Multipath-based Protocols, Heterogeneity-based Protocols, quality of service (QoS)-based Protocols etc. Clustering is used to protract the lifetime of the wireless sensor networks. It involves grouping of sensor nodes into clusters and electing cluster heads (CHs) for all the clusters. CHs collect the info from respective cluster’s nodes and forward the aggregated data to base station. In this paper we present the study of various clustering based energy efficient routing protocols of wireless sensor networks and compared them on various parameters. like Delivery Delay, Algorithm Complexity, Energy Efficiency, Load Balancing.
