Analyzing transmission of data packets in heterogeneous wireless sensor networks using z-sep in different energy levels and area ranges

Abstract

We have learnt a lot about Wireless Sensor Networks (WSNs) especially about heterogeneous WSNs, these have two different types of nodes namely normal nodes and advanced nodes which transmit data in completely different ways to the base stations. The transmission of data in heterogeneous WSNs is done using Z-SEP. Z-SEP stands for Zonal Stable Election Protocol. It is an improved version when compared to SEP and LEACH. SEP stands for Stable Election Protocol which has clustering hierarchy to transmit data from nodes (or) clusters to the destination. LEACH stands for Low Energy Adaptive Clustering Hierarchy in which there is not possibility of selecting a cluster head as in the other two. In Z-SEP the network found is separated into zones and the transmission happens through clustering technique. In the work we are analyzing the transmission of the data packets in different energy level and area ranges. We compared the performance of Z-SEP with the other two protocols (LEACH & SEP). For doing the performance analysis and simulation we have used the MATLAB simulator.
