Stable period enhancement for zonal (SPEZ)-based clustering in heterogeneous WSN

Abstract

A lot of energy is consumed in organizing the wireless sensor network. Several cluster-based protocols have been proposed to increase the lifespan of the network. The objective of WSN is the lifetime enhancement through energy efficiency. Clustering not only enhances the lifetime but also makes the network scalable and energy efficient. In this proposed work (SPEZ), we have divided the network into zones and randomly deployed the sensor nodes. Extraneous energy is supplied to some of the nodes resulting in heterogeneity. Energy-efficient approach is applied so as to increase the stability span which plays a vital role in many scenarios. Simulation and evaluation of performance validate the elongated lifetime in terms of the stable period in comparison with ZSEP, SEP, LEACH, and DEEC protocols.
