A domain-independent middleware framework for context-aware applications

摘要

This paper presents a middleware framework for context-aware applications. Instead of trying to incorporate into the middleware a set of domain-dependent adaptive policies, our approach allows the application itself to define such policies according to a chosen adaptive behavior. The middleware defines a domain-independent metamodel for context-aware applications. For applications specified according to the metamodel, the framework is able to generate code from the applications' design. We demonstrate the use of the middleware with a context-aware application in the field of mobile robotics.
