Proximity Networking

The ability for data devices, or systems, to move into a networked environment and immediately gain access to all relevant services will become a requirement for future networks. Until connecting portable devices with the computing and communications infrastructure becomes as simple as turning these devices on, people will shun the impressive potential for mobile digital services. The Proximity Networks' Project addresses this problem by designing and prototyping an architecture in which the physical proximity of a user to a network makes immediately available a local network service environment. Networks which support this kind of interaction are called proximity networks. Slides: PDF
