Abstract
To provide users with persistent services in distributed ubiquitous environments, it is required for applications and middleware to be aware of the frequent and unpredictable changes in users requirements as well as environmental conditions, also to be able to adapt their behaviour as such changes. One of the main limitations of current approaches for supporting adaptability is that applications themeselves are responsible for triggering and adaptive mechanism when the underling infrastructure notifies them about any changes. Hence, we design an adaptive middleware framework using reflection and propose the meta-meta-level to support a policy-based adaptation. We implement mobile agents (adaptation, context and meta agents) to adapt user-level and application-level changes dynamically for mobile users and applications.
