Mesh networking goes industrial
News Mesh networks work using a series of nodes -- typically very small, low-cost PCs with flash disks in place of hard drives -- to extend a Wi-Fi network from a broadband cable or satellite connection over large areas.

Warchalking: London Wi-Fi guerrillas take tips from hobos
News But warchalking is remarkable because it is based on an ad hoc process of people discovering Wi-Fi nodes -- whether commercial or not -- and signalling their presence with chalk symbols. The first attempt at drawing up symbols resulted in three...

Home Office responds to Facebook criticism
Blog Ask any network security theorist: once you have identified the nodes with the most connections in a network, if you want to disable or destroy that network then you disable or destroy those nodes. The Home Office has given a response to Facebook's...
