Planetary Internet

Info:

The World Wide Web is not truly world wide. There are places were Internet access is limited or even non-existent. There is a need for a planetary Internet. In order to get access to the Internet from any place on the planet, wireless access points need to put into place to connect remote locations. Typically LEO (Low Earth Orbit) satellites are used to deliver the data to different parts of the network. Cisco has a router in low earth orbit called CLEO.

There are various projects in place to setup wireless access points for people that have no Internet access:

These networks use the networking concept called Delay/Disruption Tolerant Networking (DTN). Since the networking devices are not continuously connected, data is transferred by doing a store-and-forward until the data reaches the destination. Routing is a concern in a DTN, because there may be delay in communicating to the next available path in the network.
