Research on Context-Awareness Service Adaptation Mechanism in IMS under Ubiquitous Network. |
Abstract | ||
|---|---|---|
The service adaptation mechanism is one of the key issues in ubiquitous network. However, most of the proposed approaches of service adaptation are either not context-aware or based on a specific definition of context in specific environment. This paper presents a context-aware service adaptation mechanism under ubiquitous network relying on user-to-object, space-time interaction patterns which helps perform service adaptation according to user's contexts (such as preferences and habits), network context, service context and device context. The contribution of this paper is to propose: 1) importing user similarity into the service adaptation process and also considering users' trust value; 2) similar users-based service adaptation algorithm (SUSA) is proposed, by combining entropy theory and fuzzy analytic hierarchy process algorithm (FAHP). Evaluation results show that the service adaptation approach based on context-aware, user similarity and SUSA algorithm outperforms the traditional service adaptation algorithm in the accuracy aspect. © 2012 IEEE. |
