Energy Efficient Two Hop Clustering for Wireless Sensor Networks

A wireless sensor network (WSN) can be described as a collection of sensor nodes which co-ordinate to perform some specific action. Unlike traditional mobile and ad-hoc networks, WSNs depend on battery, dense deployment of nodes in a given physical space and co-ordination to carry out their tasks. In the past few years, there has been lot of research work took place in the area of routing in WSNs and it is proved that the cluster based routing is the one of the best approach to improve the lifetime of the network. The proposed THC protocol makes some assumptions for efficient data routing and network lifetime longevity. The THC protocol transmits its aggregated data to the collecting base station using multipath communication compared to direct communication in LEACH. The results show that THC protocol performs very well and increases the network lifetime.
