The Quest for a Killer App for Opportunistic and Delay Tolerant Networks

Free registration required

Executive Summary

Delay Tolerant Networking (DTN) has attracted a lot of attention from the research community in recent years. Much work has been done regarding network architectures and algorithms for routing and forwarding in such networks. At the same time as many show enthusiasm for this exciting new research area there are also many sceptics, who question the usefulness of research in this area. In the past, the authors have seen other research areas become over-hyped and later die out as there was no killer app for them that made them useful in real scenarios. Real deployments of DTN systems have so far mostly been limited to a few niche scenarios, where they have been done as proof-of-concept field tests in research projects.
