Context data are updated frequently due to the dynamic changes of the various sensor values and the situations of application entities. Without a proper management, the stored contexts will become different from those of the real-world. Those invalid contexts will cause context inconsistency problems and thus should be eliminated at the right time and in an appropriate manner. In this paper, we propose a context inconsistency management scheme based on context elimination rules that describe the semantics of context invalidity to solve context inconsistency problems. The proposed rule-based scheme will enable users to easily specify elimination conditions for inconsistent contexts. Our performance evaluation shows that the rule processing overhead is compensated for by virtue of the well-maintained repository of the stored contexts.
