Energy Efficient Scheme for Clustering Protocol Prolonging the Lifetime of Heterogeneous Wireless Sensor Networks

In recent advances, many routing protocols have been proposed based on heterogeneity with main research goals such as achieving the energy efficiency, lifetime, deployment of nodes, fault tolerance, latency, in short high reliability and robustness. In this paper, we have proposed an energy efficient cluster head scheme, for heterogeneous wireless sensor networks, by modifying the threshold value of a node based on which it decides to be a cluster head or not, called TDEEC (Threshold Distributed Energy Efficient Clustering) protocol. Simulation results show that proposed algorithm performs better as compared to others.
