e-ONE: Enhanced ONE for Simulating Challenged Network Scenarios
Delay Tolerant Network (DTN) empowers sparse mobile ad-hoc networks and other challenged network environments, such as interplanetary communication network or deep sea communication network, where traditional networking protocols either fail to work completely or do not work well. The Opportunistic Networking Environment (ONE) Simulator has gained considerable popularity as an efficient tool for validating and analysing DTN routing and application protocols. It provides options for creating different mobility models and routing strategies as per the users’ requirements. Nowadays, challenged networks such as rural internet connection, social networks, post-disaster communication systems, etc. use DTN along with some hybrid infrastructure networks. Incorporating such real life network systems in ONE needs extensive modification of the same. In this paper, we present the enhanced ONE (e-ONE) simulator as an extension of ONE to facilitate simulation of challenged networks and describe the enhancements we have added to the ONE. As a case study, we consider a challenged network, which we call a latency aware 4-tier planned hybrid architecture designed for post-disaster management. We describe, in detail, how this enhanced version of the ONE simulator is useful in analysis and evaluation of the scenario considered.
