Abstract

Developing distributed embedded systems based on Internet and Web technologies is a relative new trend in computer technologies. The paper shows the tree-layer client-server model in developing web-based distributed embedded systems. It also presents a model-driven approach for generating quality-of-service (QoS) adaptation in Distributed Real-time Embedded (DRE) Systems. Our control task model consists of the target task to be controlled, the adaptation task that implements the control algorithm. We have built a prototype of a middleware system which verifies our control model and shows the soundness of our approach. A detailed experimental analysis is also presented in this paper.
