Implementing Multicasting and Broadcasting of Multimedia Data in ONE Simulator

Abstract

The Opportunistic Network Environment (ONE) simulator is a Java based simulator intended for research in Delay Tolerant Networks (DTNs). Apart from allowing users to simulate different DTN scenarios rapidly and in a versatile manner, it also offers an easy way to generate results from the simulations performed. Although the ONE simulator is widely accepted among the DTN research community as a standard DTN simulator, it supports only some limited features of DTN. The current release of the ONE simulator (version 1.6.0) only supports dissemination of messages with textual content over unicast mode of communication. The propagation of messages containing multimedia content and support for multicasting and broadcasting mode of communication are still not included in it. In this paper, we propose to implement the multicast and broadcast modes of communication and dissemination of multimedia content in the ONE simulator. We augment the ONE simulator version 1.5.1 RC-2 to incorporate the proposed features. Two sets of experiments are conducted to validate the implementation of the proposed features. The experimental results demonstrate successful implementation of both the features in ONE simulator.
