Submission + - Home WiFi routers could operate as emergency network, say scientists (networkworld.com)
An anonymous reader writes: German researchers have proposed using home Wi-Fi routers as a backup mesh network in the event that cell and phone systems in cities and towns are overwhelmed during emergencies. In a recently-published paper, researchers at the Technical University in Darmstadt in Germany describe how home routers could be linked to one another to form a huge informal backbone for use by fire, police and ambulance services. Most recent home routers can support such a system without modification as long as they allow for the creation of an open 'guest' network running in parallel to the user's secured Wi-Fi access, that is firewalled from it.
