Delay Tolerant Networking (DTN) is a promising technology that aims to provide efficient communication between devices in a network with no guaranteed continuous connectivity. Most existing routing schemes for DTNs exploit the advantage of message replication to achieve high message delivery rate. However, these schemes commonly suffer from large communication overhead due to the lack of efficient mechanisms to control message replication. In this paper, the authors give a brief survey on routing protocols designed for DTNs and evaluate the performance of several representative routing protocols including Epidemic, Spray and Wait, PRoPHET and 3R through extensive trace-driven simulations.
