Clustering based routing protocols: A comparative study

A wireless sensor network consists of small low cost sensor nodes and having a limited transmission range. Their processing, storage capabilities and energy resources are limited. These networks collect information from nodes and transmit to base station for further processing. Energy and storage capabilities are a major problem to perform routing in wireless sensor network with such limitation of low power. There are many routing protocols like: location based, multipath, data centric, mobility based, hierarchical routing, hybrid routing etc. An Optimal Clustering technique can reduce the energy consumption in WSN and increase the lifetime of the network. In this paper we have studied and compared different clustering based energy efficient routing protocols of wireless sensor networks on various parameters.
