Abstract

In this paper we have developed a method for an efficient Quality-of-Service provision and adaptation in dynamic, heterogenous systems, based on our Matrix framework for resource management. It integrates local QoS mechanisms of the involved devices that deal mostly with short-term resource fluctuations, with a global adaptation mechanism that handles structural and long-term load variations on the system level.Moreover, we introduce an application adapter, the closed-loop control model for resource monitoring and adaptation, the different resource reallocation policies used within global adaptation, as well as the deployment of our approach in the context of video streaming and video stream adaptation.
