Component-based multimedia application for fine-grained migration

Abstract

With the advent of powerful mobile devices such as smart phones, tablets and ultraportable laptops, users today are surrounded by a wide array of heterogeneous devices that are capable of downloading, processing and displaying multimedia. The multitude of devices paired with advancements in wireless networks and transfer rates, has granted users access to new application domains such as mobile video-conferencing and mobile on-demand streaming while being on the move. There is however a drawback with current solutions as they are often device or architecture specific and require the user to install multiple versions of the same application on all their devices. We propose using process migration in order to take advantage of the multitude of devices, without the need of device specific applications. This thesis focuses on the design and implementation of a Web-TV application. We have split the application into distinct components that are responsible for certain tasks such as user interaction, playback and network handling. This is done in order to aid fine-grained mobility by migrating the various components among several devices. In order to utilize a wide range of heterogeneous devices without adding cross-platform complexity, the application is designed for the Android platform. The goal of this thesis is to show the benefits of component migration and as a benchmark for further development of our migration platform.
