Performance Comparison of Four Unicast Routing Schemes in DTNs

Disruption Tolerant Network (DTN)s has been proposed to provide data communications in challenging network scenarios where an instantaneous end-to-end path between a source and destination may not exist. In this paper, the authors focus on comparing the performance of four recently proposed unicast routing schemes, namely Multi-hop Routing with Custody Transfer (MRCT), Two-Hop Relay with Erasure-Coding (THEC), MaxProp, and Prophet. 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.
