Power is a critical, limited, and shared system resource.
Traditionally, the operating system plays a major role in managing such resources. We also believe that the applications hold an important key, in the application-specific constraints and opportunities for saving energy that can be known only at that level. Therefore, our approach is to have the needs of the applications be the driving force for the development of power management functions in the operating system and of a power-based API that allows a partnership between applications and the system in setting energy use policy. The primary focus of this research is in enabling multimedia web access from slow, expensive and congested networks using application level techniques. We utilize transcoding as the enabling technology.
