Research of Context-aware Component Adaptation Model in Pervasive Environment

With rapid development of computer technology, adaptive objects have been changed to distributed components and services. Furthermore, though distributed applications have been larger and more complex, all the system can be regarded as the connection of different components by the rules from the point of software architecture. In pervasive environment, there are lots of computing and communication devices which connect the thinking and the activities. The applications in this kind of environment are usually context-aware and can provide more flexible services based on the affection of the contexts. Traditional component-based middleware are almost lack of support for pervasive computing. So we extend traditional component adaptation methods and put forward a context-aware component adaptation model CACAM as well as according algorithm named CACA. Results show this model can support the context-aware component adaptation efficiently.
