Resource-aware configuration of ubiquitous multimedia services

Abstract

Emerging ubiquitous multimedia services are expected to be available any time, anywhere, and using different computing devices. We present 2K/sup Q/, an architecture that enables such a dynamic and customized delivery of multimedia services. In 2K/sup Q/, a multimedia service can be delivered by multiple service configurations, each of which involves a different set of service components. For each client, the appropriate service configuration is chosen based on the current end-to-end resource availability. We have implemented a prototype of 2K/sup Q/ as part of the 2K operating system. As a proof-of-concept, we have also built a video streaming service on top of 2K/sup Q/. Our experiments show the soundness of 2K/sup Q/.
