Abstract
Ubiquitous computing allows application developers to build a large and complex distributed system that can transform physical
spaces into computationally active and intelligent environments. Ubiquitous applications need a middleware that can detect
and act upon any context changes created by the result of any interactions between users, applications, and surrounding computing
environment for applications without users’ interventions. The context-awareness has become the one of core technologies for
application services in ubiquitous computing environment and been considered as the indispensable function for ubiquitous
computing applications. The need for high quality context management is evident to the component-based middleware for it forms
the basis of the component adaptation and the component deployment in the pervasive computing. Therefore, we suggest a holistic
approach where context management is an integral part of a more comprehensive adaptation enabling middleware, thus enabling
the development and support of context-aware, component-based applications.
