Time to start the internet over with? New Scientist reports on the burgeoning world of meshnets:
The internet is neither neutral nor private, in case you were in any doubt. So some people are building their own net from scratch.
Across the US, from Maryland to Seattle, work is underway to construct user-owned wireless networks that will permit secure communication without surveillance or any centralised organisation. They are known as meshnets and ultimately, if their designers get their way, they will span the country.
Each node in the mesh, consisting of a radio transceiver and a computer, relays messages from other parts of the network. If the data can’t be passed by one route, the meshnet finds an alternative way through to its destination.
While these projects are just getting off the ground, a mesh network in Catalonia, Spain, is going from strength to strength. Guifi was started in the early 2000s by Ramon Roca, an Oracle employee who wanted broadband at his rural home. The local network now has more than 21,000 wireless nodes, spanning much of Catalonia. As well as allowing users to communicate with each other, Guifi also hosts web servers, videoconferencing services and internet radio broadcasts, all of which would work if the internet went down for the rest of the country.
So successful is the community model that Guifi is now building physical fibre-optic links to places like hospitals and town halls where it can help carry the heaviest traffic.
