Abstract: Due to high dynamic computing environments of ubiquitous computing, it poses many challenges for software middleware technologies. The component-based middleware systems should possess self-adjusting functions for adapt to internal and external environments variation. This paper firstly describes a middleware called SCUDWare for smart vehicle space in ubiquitous Computing. Then we propose a middleware requirement model including users¡¯ and resources¡¯ variable requirements. After that, a component dynamic behavior model is presented. Next, an adaptive requirement framework is given in detail, which can automatically tune middleware configuration parameters, and conduct a safe and dynamic component composition to preserve the middleware QoS requirements. Finally, it is prototyped and validated by using a mobile music program to analyze performance of this framework.
Keywords: Ubiquitous Computing, Adaptive middleware, Component-based technology
