Analysis of Creido Enhanced Chord Overlay Protocol Under Different Movement Models in Delay Tolerant Networks

Abstract

Delay Tolerant Network (DTN) is an enlivening area to delve in owing to its rudimentary characteristics like intermittent links, variable delays etc. and its physiognomies of applications wherever traditional networks like sparse and emergency mobile ad-hoc networks fails. These applications are aided extensively if the performance metrics are recuperated. In this article a novel plot to increase the end to end bundle delivery ratio by assimilating CREIDO bundles in chord overlay network. This periodic bundle invokes the stabilize function of chord overlay protocol to make the overlay topology robust during node join and exits. In this article, OverSim framework of OMNeT++ is used under different mobility models to analyse the performance metrics of CREIDO bundles. Thus the results obtained were encouraging and outsourced the existing protocol in aspects of Bundle Delivery Ratio and throughput.
