In this talk, we will provide an overview of the Daedalus Project, which is developing technology for the seamless integration of heterogeneous wireless subnetworks, in particular, mobile routing, transport, and application adaptation of multimedia data types across wide ranges in bandwidth and latency. This technology is being deployed in the Bay Area Research Wireless Access Network (BARWAN), being constructed with technology from IBM, AT&T/NCR, Metricom, Hybrid, and Hughes. The testbed includes in-building and wide-area wireless technologies, including satellite direct broadcast and wireless cable modems. The work is joint with Professor Eric Brewer.
