A model-based design framework to achieve end-to-end QoS management


A significant challenge in constructing distributed real-time embedded systems for highly dynamic environments lies in assuring the Quality-of-Service (QoS) requirements. The dynamism inherent in the environment renders it impossible for static provisioning of the QoS requirements, thereby making it necessary to consider adaptive techniques. Feedback adaptation traditionally is the prerogative of control engineers, while, the DRE system must be designed by domain engineers. In this paper we propose the use of model-based techniques to raise the abstraction of control theoretic techniques and make them available to domain engineers. The paper presents, a graphical modeling environment, that we call Dynamic QoS Modeling Environment (DQME), that facilitates the design of QoS adaptive applications for DRE systems. DQME facilitates capture of the QoS adaptation as well as the functional aspects of the DRE system. A case study has been presented that demonstrates the use of DQME.
