The WiNGS laboratory hosts an outdoor, vehicular, wireless testbed with support for various wide-area experimentation efforts, called MadBed.
Currently, MadBed consists of two wireless nodes mounted on specific city-buses operated by the Madison Metro Transit System.

The testbed nodes are remotely accessible and programmable. Each node consists of a Intel Core-2 Duo 2.0 GHz laptop, with WiFi interfaces, a 3G EVDO rev. A interface, and a vehicular mobile router for providing Internet access to the bus passengers. We also have a remote bus tracking interface that allows us to locate the position of the buses in real-time.
Access to this testbed is currently limited to UW-Madison faculty and students. Please email Prof. Suman Banerjee for access and account information.
