Summary on Grant Application Form |
|
The proposed project will address the requirement to support highly configurable distributed multimedia composed of active objects. In particular, we aim to respond to dynamic work patterns and the requirement for user mobility. These modes of working require applications to adapt to changing hardware and software environments. For example, the system can maintain the user's multimedia connections as he moves around a building. The research issues to be addressed are, first, the separation of concerns between the applications and their management. We propose to achieve this separation using an event -orientated approach. We propose to base this on the existing Cambridge work on declarative work on event-driven rules for reconfiguration; we shall evaluate our approach by building an application framework for mobile-user multimedia. Second, these adaptive multimedia applications have demanding QoS and consistency constraints, while met during reconfigurations as well as normal running. The challenge is to meet these constraints, which must be met while the application continues to run smoothly. We propose to build upon the Djinn framework developed at QMW for this purpose, by building and instrumenting a transactional re-configurable mechanism. Acorn computers will be an industrial collaborator, and have agreed to provide labour, hardware and their real-time Galileo operating system.
