The Bay Area Research Wireless Access Network (BARWAN)

Wireless data services have thus far been more promising than successful. We believe that future mobile information systems must be built upon heterogeneous wireless overlay networks, extending traditional wired and internetworked processing "islands" to mobile hosts over coverage areas ranging from in-room, in-building, campus, metropolitan, and wide-areas. In this paper, we describe a new wireless data networking architecture that integrates diverse wireless technologies into a seamless internetwork. It is being implemented in the BARWAN testbed in the San Francisco Bay Area.
