By separating the concerns of an application into components responsible for distinct tasks, these components can run on the different devices where they perform best. As a step(More)
In order to leverage the potential of the device diversity of users, we aim to provide a middleware solution where parts of a multimedia application migrate to different devices and take advantage of more processing power and different I/O capabilities. The middleware is fully designed, and partially implemented and evaluated. Preliminary results from(More)
