摘要：Delay Tolerant Networking (DTN) is a promising technology that aims to provide efficient communicationbetween devices in a network with no guaranteed continuous connectivity. Most existing routing schemesfor 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 mechanismsto control message replication. In this paper we give a brief survey on routing protocols designed forDTNs, and evaluate the performance of several representative routing protocols including Epidemic, Sprayand Wait, PRoPHET, and 3R through extensive trace-driven simulations. Another objective of this work isto evaluate the security strength of different routing schemes under common DTN attacks such as the blackhole attack. The results and analysis presented in this paper can provide useful guidance on the design andselection of routing protocols for given delay-tolerant applications.
