An Adaptive and Semantic Component Model for Adaptive Middleware in Ubiquitous Computing Environments

In ubiquitous computing environments, the software component model with semantic information and adaptation to satisfy various resources constraints and component interdependence is needed. This paper mainly presents an adaptive and semantic component model for an adaptive middleware. The model consists of an adaptive component model and a semantic virtual agent model. The contribution of our work is twofold. First, we present a resource-aware component interdependence graph to describe dynamic interdependent relationships among components. Second, we put forward a semantic interface of the semantic virtual agents model. As a result, the model is applied into a mobile music program to evaluate its performance.
