Disconnected, Non end-to-end networks Presented by: Khaled Harras
2
So what happens when both wired and wireless communication break down?!

Epidemic Routing
5
The rise of the Interplanetary Internet….!

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….
