Abstract

Context-aware computing is one of the research fields in pervasive computing and mobile computing. Context-aware systems can react to the user's preference according to the circumstances called context including location, time and other environment conditions. Many context-aware computing paradigms were developed in recent year; however, it is difficult for the present systems to extend the application domains and interoperate with other service systems due to the problem of heterogeneity among systems. In this paper, an extendible context-aware service system importing the concept of context independence is proposed and designed. The main idea of context independence includes the physical context independence and the logical context independence. The approaches of constructing context independence are also provided for the proposed system architecture. The context-aware system thus can easily integrate different service domains and diverse devices into a unifying environment.
