Context and Context Management

Abstract

The user and user requirements are the main important concerns to design a pervasive computing system. The context of a user or device is another essential element in designing a context-aware pervasive computing system. This chapter is focused on what is the context, the variety of contexts, and the impact of that context information in developing a context-aware computing system. This chapter has also discussed several context-aware computing modelling as a part of the state of the art. On the line of existing models, this chapter has proposed 8C—a new context-aware computing model. The chapter also describes how RFID and sensors are used to sense context and shares the context information to further layers of context-aware computing system architecture. This chapter concludes with the context, its interpretations, storage and other important aspects.
