Disconnected, Non end-to-end networks Presented by: Khaled Harras

So what happens when both wired and wireless communication break down?!

Wireless Ad Hoc Networks Connected end-to- end ad hoc networks A B A B Disconnected ad hoc networks

Epidemic Routing

The rise of the Interplanetary Internet….!

Similar Problems, Common Solutions Fiber Satellites Cable Mobile/Wireless WDM Nomadic Terabit communications low delay Self-organizing FTP/TCP/IP Short-haul communications Terrestrial Internet Standards Opportunity for leverage S-band X-band Ka-band LEO Constellations Mars Network Deep-space Optical Megabit communications high delay Long-haul communications Space Internet Standards File-based Operations InterPlaNetary Internet Architecture

So where is the problem??... ….Only when planets come in the way!

New, expandable architecture…

Is all this “way out there”??!! Are there other applications??

YES!!.... Extreme challenged networks.

The rise of Delay Tolerant Networks (DTNs)…..

“Regions” instead of “Internets” in DTNs

Persistent Storage and Custody Transfer

There are even more down-to- earth (literally!) applications….
