Dual Cluster Head Routing Protocol with Super Node in WSN

This paper introduces dual cluster head routing protocol with super node (DCHRP4) having dual cluster head with four level of heterogeneity to improve the lifetime of a wireless sensor network. The main objective is to reduce the number of selection of cluster head so that the energy consumption can be minimized. In a clustering based sensor network cluster head does all the work from collecting to transmitting data to sink. Therefore, Cluster head loses its energy very fast. Energy plays an important role in efficient management of sensor network. Due to the handling of multiple tasks, energy of a cluster head is lost very fast. So, the paper focuses on reduces the energy consumption, improving the stability, the lifetime of the network, and throughput. From the simulation performed it is observed that the stability period of DCHRP4 upgrade 56.11% over enhanced threshold sensitive stable election protocol (ETSSEP) and twice and more than thrice over threshold sensitive stable election protocol (TSEP) and stable election protocol (SEP) respectively. The overall lifetime of DCHRP4 also upgrade by 8.29% and 49.22% over ETSSEP and TSEP respectively whereas about thrice in comparison with SEP. The throughput improved by 7.75% over ETSSEP, twice over TSEP and SEP respectively.
