Virtual Repositories in Delay Tolerant Networks

The lack of contemporaneous end-to-end paths often char- acterize mobile computing environments, for which Delay Tolerant Networking is designed. In this work, we present a novel routing protocol usingVirtual Repositories to assist in location-based forwarding when the location of a desti- nation node is unknown. We compare the protocol to other existing protocols under two mobility models, Random Way- point and Random Walk, and show its competitiveness while illustrating areas for further work and improvement.
