Performance Investigation of Energy Efficient HetSEP for Prolonging Lifetime in WSNs

Abstract

In this work, we investigate the performance of heterogeneous stable election protocol (HetSEP) for prolonging the network lifetime. An order-5 heterogeneous energy network model is proposed in this work that can defines the order-1, order-2, order-3, order-4, and order-5 heterogeneity. We consider the SEP protocol to calculate the lifetime of the network and consequently describe its accomplishments as HetSEP-1, HetSEP-2, HetSEP-3, HetSEP-4, and HetSEP-5. The SEP protocol is HetSEP-1 in which all the sensor nodes have same amount of energy. The HetSEP-2, HetSEP-3, HetSEP-4, and HetSEP-5, contain two, three, four, and five orders of energy, respectively. The network lifetime increases as increasing the order of heterogeneity. The HetSEP-2, HetSEP-3, HetSEP-4, & HetSEP-5, prolong the lifetime of the network 100.39%, 126.12%, 186.56%, & 285.67%, in respect to the increase the energy of the network by 65.0%, 72.58%, 107.10%, & 208.40% with respect to the HetSEP
