Abstract

Existing context-aware middleware are designed to automatically adapt its behavior to changing environment such as effectively selecting services for adaptation according to the user’s current context. However, with the increase of pervasive services and the kinds of sensors, the importance of information quality becomes more urgent. We should continuously monitor/capture and interpret the environment related information efficiently to assure efficient context awareness. Many attentions have been paid to the research of the context-aware pervasive applications and context-aware service adaptation. However, little of them pay attention to the quality based service adaptation. Therefore, we propose a quality management middleware to support QoC management for service adaptation. By using this framework, we can configure different strategies to refinery raw context, discard duplicate and inconsistent context so as to protect and provide QoS-enriched context information of users to support context-aware service adaptation.
