An Adaptive Context-Aware and Event-Based Framework Design Model

Context-aware and proactive technologies have been continuously used over the past years to improve user interaction in areas such as searching and information retrieval, health care and mobile computing. Although there have been significant advances in context-aware systems, there is still a lack of approaches that model and implement context-aware proactive applications involving the combination of context and distributed events. In this paper we address these issues by defining a context-aware event model, a new context-aware publish subscribe scheme and a distributed event-based framework. Our proposed event model is implemented as a context-aware distributed eventbased framework that provides the necessary infrastructure to publish and deliver events based on a component's context. In summary, we are able to leverage context as part of our event model and bring behaviour context-aware adaptation to publication and subscription of events.
