Über dieses Buch

This book introduces context-aware computing, providing definitions, categories, characteristics, and context awareness itself and discussing its applications with a particular focus on smart learning environments. It also examines the elements of a context-aware system, including acquisition, modelling, reasoning, and distribution of context. It also reviews applications of context-aware computing – both past and present – to offer readers the knowledge needed to critically analyse how context awareness can be put to use. It is particularly to those new to the subject area who are interested in learning how to develop context-aware computing-oriented applications, as well as postgraduates and researchers in computer engineering, communications engineering related areas of information technology (IT). Further it provides practical know-how for professionals working in IT support and technology, consultants and business decision-makers and those working in the medical, human, and social sciences.

Chapter 1. Introduction to Context-Aware Computing
Abstract
This chapter aims to introduce the concept and foundation of context-aware computing. Variety kinds of services and applications of context-aware computing can be seen everywhere with a wide range of application domains such as Information Communication Technology (ICT), Health Science, Humanity, Social Science, etc. Most applications and services of context-aware computing are not only in the imaginary any longer. Many innovations in context-aware computing are now under the development to achieve the ultimate goal which is to support the convenient use for the users.

Chapter 2. Context and Its Awareness
Abstract
This chapter aims to introduce the definition of context and its awareness, which are shown through the review of existing works from the early and the current state of context-aware computing. The categories, the characteristics, and the property of context are described. The context-aware architecture is discussed in this chapter. The common components of context-aware applications can be summarized into three components including perceiving component, thinking component, and acting component. Additionally, some perspectives for context definition as social context, context categorization and context awareness as personalized and rationalized awareness are emphasized at the end of this chapter.

Chapter 3. Elements of Context Awareness
Abstract
This chapter describes some essential elements of context-aware applications including context acquisition, context modeling, context reasoning, context distribution, and context adaptation. Context acquisition involves gathering context from the users and the environment. It has to engage with various kinds of sensors. Context modeling which is also called context representation is needed because of the necessary to have the common understanding between the system and its components. It also has to deal with the relationships and dependencies of different types of contexts. Context reasoning involves creating new knowledge and deducing better understanding based on the available context. Context distribution is to deliver the appropriate information or the services to the users. It plays the leading roles, especially for the large-scale network system. Finally, context adaptation involves the adjustment of application’s behavior so that the appropriate response can be obtained.

Chapter 4. Communications for Context-Aware Applications
Abstract
This chapter accounts for the foundation of communication for context-aware applications. Some relevant communications are introduced including communication network, sensor network, body area network, and social network. For communication networks, the foundation of the communication system is described together with the current popular wireless systems. The sensor network is introduced to provide the whole idea of how to manage many different types of sensors. Body area network becomes popular nowadays, especially for healthcare application domain. Since this network involves a lot of small size of body sensors, some significant concerns for gathering body context is discussed in this chapter. Finally, the social network is introduced as the important communication for people nowadays. Understanding the social behavior appropriately enables to provide the appropriate feedback to the group and the individual user. Some measurements of social network analysis are also shown in this chapter.

Chapter 5. Security for Context-Aware Applications
Abstract
With the advance of wireless technology, the contexts are transmitted through fast and efficient communication method. All computing activities occur around the users obtrusively. To satisfy context-aware applications, it is tough to maximize functionality but remains strong security at the same time. This chapter introduces the principle concept of security required for context-aware applications. The security, in general, is firstly introduced. Some security attacks and countermeasures are reported. Some security recommendations for context-aware applications and the existing security protocols are also discussed in this chapter. The ultimate goal of this chapter is to promote sense of security awareness for the readers who can be both the developers and the users.

Chapter 6. Context-Aware Middleware and Applications
Abstract
This chapter focuses on reporting some context-aware middleware and applications impacting the variety of application domains of context-aware computing for decades so that the readers will be able to utilize this kind of application appropriately. However, the main focus is on smart environments such as smart home, and personalized environments. At the end of this chapter, the future trends in smart environments for healthcare and education domains are suggested based on the evolution of existing works and some significant concerns.
