Performance Comparison of RAPID, Epidemic and Prophet Routing Protocols for Delay Tolerant Networks
These opportunistic networks or DTN are the class of networks where the nodes do not have contemporaneous connections, but intermittent connections. In DTN, the main characteristic of packet delivery is large end-to-end path latency and a DTN routing protocols has to cope with frequent disconnections. The lifetime of packet would have large effect on the performance of routing protocols in DTN as the delay is large in DTN. In this paper, the authors have investigated the performance of three different routing protocols namely Epidemic, Prophet and RAPID against varying message TTL. For the simulation they have used Opportunistic Network Environment (ONE) Simulator.
