DTIPN: delay tolerant IP networking for opportunistic network applications

This paper proposes delay tolerant IP networking (DTIPN), an alternative architecture for delay and disruption tolerant networks. This architecture directly fits into the Internet protocol architecture, still providing delay and disruption tolerant support for application message delivery without relying on the well-known Bundling. DTIPN takes IP packets as asynchronous data delivery units, identifying the location of hosts by IP addresses. We have implemented the architecture and carried out several experiments with 10 intermittently-connected or mobile nodes in the campus of the University of Tokyo. The result, on our prototype implementation, indicates that DTIPN architecture has well-adaptive nature to the Internet with providing practically useful performance.
