ABSTRACT
The computing world has grown with devices from mainframe and personalized desktops to tablets and smartphones in the present world. The backbone of the Internet is growing with well advances in wireless technology and communications with application-specic processors. Cyber-physical systems use these advance wireless networks with sensors to connect humans with physical embedded computing world [1]. Computers are envisioned as machines that perform the computation as we enter for a task to be performed and leave when it nishes. Ubiquitous and pervasive computing is a concept that changes this perception of computing by using the information gathered by various devices and provides a computing environment that appears anywhere and everywhere. There are various areas of research where ubiquitous computing can be achieved through the use of wireless networks and the Internet technology. Some of the areas are as shown in the Figure 14.1. We discuss some of the use cases related to these areas further in this chapter.
