Transparent extention of existing applications for mobile computing

Mobile computing devices together with an ever growing land-based and
wireless communication network infrastructure are the existing technical
prerequisites for continuous access to networked services. This relieves
users from being bound to their desktop computers and lets them spread out
into the world. But using the different mobile facilities often requires a
lot of special concern and there is no straight-forward solution towards an
integrated mobile environment. This paper examines an approach to extend
existing systems by transparently introducing a mobility service system to
meet the special needs of mobile users. Typical mobile communication problems
such as frequent disconnection, low bandwidth or a changing network environ-
ment are hidden embedding the user into a supporting overall networked infra-
structure but still providing his familiar workplace environment.
