Performance Comparison of Unicast Routing Schemes in DTNs

Delay and Disruption Tolerant Network (DTN)s have been proposed to address data communication challenges in network scenarios where an instantaneous end-to-end path between a source and destination may not exist, and the links between nodes may be opportunistic, predictably connectable, or periodically-(dis)connected. In this paper, the authors focus on comparing the performance of different proposed unicast routing schemes. In particular, they conduct performance studies for different DTN scenarios, e.g., DTNs with different node densities, DTNs with different mobility models, networks with different percentage of nodes supporting DTN functionality, etc.
