Abstract

An in-depth study of Stable Election Protocol (SEP) revealed that, distance was not considered in selecting the cluster heads in the network. This allows a distant node that is selected as the head to dissipate huge energy in transmitting data to the Base station (BS). It was further observed that, whenever the Base station is relocated outside the field, the energy consumption of the network is high and hence shortening the lifetime of the network. In this paper, a Gateway-SEP protocol is proposed. The G-SEP modified the election probability of electing cluster heads by considering the distance, average distance and residual energy of the advanced nodes. The scheme also introduced a gateway node at the centre of the network and then installed the BS outside the field. Simulation results using MatLab R2017a showed that, the G-SEP performs better than Zonal-Stable Election protocol (ZSEP) in terms of coverage, stability period, throughput and network lifetime.
