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

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

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

  4. Epidemic Routing

  5. The rise of the Interplanetary Internet….!

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

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

  8. New, expandable architecture…

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

  12. YES!!.... Extreme challenged networks.

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

  14. “Regions” instead of “Internets” in DTNs

  15. Persistent Storage and Custody Transfer

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