Composite context information design and model approach for adaptive service decision

Context-aware computing has been considered as promising topic in pervasive computing area, but a review of the existing approaches shown that developing diverse application services in this area is still motivated based on the analysis of existing approaches in literature. The purpose of this study, is proposed the composite context information model to provide the knowledge that is determine the path of adaptive service configuration in mobile environment. First of all, our research is defined the composite context information in perspective of this study, and based on this definition, is proposed the approach of master data modeling to configure the composite context information. It is show to can resolved the problem related with data processing, among a lot of difficulties that the proposed context information based system is shown.
