Movement Models Based Performance Comparison of Routing Protocols in Delay Tolerant Networks

Vinit Kumar, Anita Singhrova

Delay-tolerant networks have the great potential to connecting devices and regions of the world that are being presently under-served by current networks. A challenge for Delay Tolerant Networks is to determine the routes through the network without having an end to end connection at any given instant of time. In DTN the routing of packets is done using store-carry-forward mechanism. In this paper, four popular routing protocols in DTN namely; Epidemic, Direct Delivery, Spray & Wait, Prophet have been considered for performance evaluation. The performance of these routing protocols has been evaluated using Shortest Path Movement models
