Research on Technology for Context Awareness in Pervasive Computing Environment

Abstract

To facilitate the development and deployment of context-awareness application in pervasive computing, a context-awareness framework needs to be used to adapt to different execution contexts and hide heterogeneity from applications. Therefore, after examining the concept of context and context awareness computing and some key technologies for context-awareness in pervasive computing, including context acquisition methods, context modeling and reasoning, and programming context etc., a dynamic context-awareness framework is put forward to effectively manage the context information and services mobility which has not been supported in the previous models. The model provides the standard interface to realize the interaction among the heterogeneous devices and hide heterogeneity from applications.
