In this paper, a performance evaluation of heterogeneous Wireless Sensor Networks using Energy-Efficient Clustering is presented. Energy- Efficient clustering are algorithms designed for heterogeneous WSN under consideration so these protocols do not work efficiently under homogenous scenarios because these algorithms are unable to treat nodes differently in terms of their energy. Here, we evaluate the performance of DEEC clustering algorithms based on stability period, network lifetime, and throughput for different levels of heterogeneous wireless sensor networks. Energy Efficient Clustering performs well under three-level heterogeneous WSNs containing high energy level differences between normal, advanced, and super-nodes in terms of the stability period. Simulation results show that the number of alive nodes varies as the network evolves and the first node dies around 1900 round. Result also shows that in Energy Efficient Clustering in Heterogeneous Wireless Sensor Networks unstable region starts very later as compared to other protocols
