Message Multicasting in Near-Real Time Routing for Delay/Disruption Tolerant Network

Delay/Disruption Tolerant Networks make communication possible in networks that enable an end user to send/receive data on small, robust networked processing devices distributed in day to day life. Delay/Disruption Tolerant Networks having numerous constraints like frequent movement, low energy devices, limited storage that certainly require different routing paradigm. The uncertain delay in the process involved may cater to undesired results. The problems faced by such network are more complex than existing underlying networks of network. For such different class of networks, designing an innovative protocol considering various limitations makes it definite/obvious to vigorously switch to multicasting approach of forwarding/flooding data packets in DTN environment. In this paper, Researchers have simulated multicasting for routing protocols in DTNs. In the previous work node connectivity is done using synthetic data traces. Researcher proposes the use of real world data traces and analyzes the impact of Multicasting approach on different routing protocol in DTN. Researchers have performed extensive evaluations of the proposed methods using simulation environment. The comparative result critically synthesizes strength and weakness of Message Multicasting approach. Also with Epidemic Oracle having oracle of past contact, it is possible to achieve high delivery ratio.
