Robustness Performance Analysis of OEERS Clustering Technique for Heterogeneous Network Models

Abstract

Objectives: To design an Optimized and Energy Efficient Routing Scheme (OEERS) for heterogeneous wireless sensor networks. Methods: In OEERS algorithm the cluster head selection is done with the probability values based on available energy levels along with optimal cluster counts and node distance from base station. Hence, nodes with higher energy and located near to base station have higher probability to be selected as cluster head (CH). Findings: In this work, analysis for OEERS has been executed to prove the robust network performance for the designed sensor network in a multi-level heterogeneous environment in terms of key network parameters such as Arrival of Dead Nodes in various stages, Number of Packets Transmitted to Base Station, Number of Dead Nodes during Each Round, Residual Energy during Each Round, Dissipated Energy during Each Round, etc. Besides this, comparative analysis has also been performed to showcase the out performance of the OEERS technique over the DL-LEACH scheme.
