Would you like to be without the

Internet access?

Only 1.5 billions out of 6.5 billions

in the world have the Internet

DTN was originally developed for

inter-planetary Internet, and was applied to wireless

planetary Internet, and was applied to wireless

networks.

We need to apply DTN to The Other Billions in

developing and developed countries.

Some of the technologies developed above

shall be evaluated for these environments.

9.2 Wireless (backbone) network

Wireless networks may be exploited

Wireless networks may be exploited

extensively for The Other Billions due to

lack of good wired backbone and access

networks.
