Wireless data services, other than those for electronic mail or paging, have thus far been more of a promise than a success. We believe that future mobile information systems must be built upon heterogeneous wireless overlay networks, extending traditional wired and internetworked processing “islands” to hosts on the move over coverage areas ranging from in-room, in-building, campus, metropolitan, and wide-areas. Unfortunately, network planners continue to think in terms of homogeneous wireless communications systems and technologies. In this paper, we describe our approach towards a new wireless data networking architecture that integrates diverse wireless technologies into a seamless wireless (and wireline) internetwork. In addition, we describe the applications support services needed to make it possible for applications to continue to operate as mobile hosts roam across such networks.
