Application adaptation through transparent and portable object mobility in Java

This paper describes MobJeX, an adaptive Java based application framework that uses a combination of pre-processing and runtime support to provide transparent object mobility (including AWT and Swing user interface components) between workstations, PDAs and smartphones. Emphasis is placed on the mobility subsystem (MS), a mobile object transport mechanism providing a high level of transparency and portability from the perspective of the system and the developer. The MS is compared to its most similar predecessor FarGo, demonstrating the advantages of the MS in terms of transparency and portability. Furthermore, a series of laboratory tests are conducted in order to quantify the runtime performance of the MS and two other systems, FarGo and Voyager
