Transparent extention of existingapplications for mobile computingRimbert

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 diierent mobile facilities often requires a lot of special concern and there is no straightforward 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 environment are hidden embedding the user into a supporting overall networked infrastructure but still providing his familiar workplace environment.
