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

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

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

4. Epidemic Routing

5. The rise of the Interplanetary Internet….!

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

10. New, expandable architecture…

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

14. YES!!.... Extreme challenged networks.

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

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

20. Persistent Storage and Custody Transfer

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