  • The aim of this book is to give a treatment of the actively developed domain of Ubiquitous computing. Originally proposed by Mark D. Weiser, the concept of Ubiquitous computing enables a real-time global sensing, context-aware informational retrieval, multi-modal interaction with the user and enhanced visualization capabilities. In effect, Ubiquitous computing environments give extremely new and futuristic abilities to look at and interact with our habitat at any time and from anywhere.

  • Delivering Voice over Internet Protocol (VoIP) services is a promising scenario for many cable operators. Unlike circuit-switched telephony, VoIP offers new opportunities for advanced and differentiated services, such as real-time call management, integrated messaging, interactive logs and ubiquitous call notification. While VoIP seems promising, it’s also daunting. VoIP is a disruptive technology that’s being fueled by a rapidly growing and highly competitive broadband market. Its success in international call traffic shows its potential for challenging existing business models.

  • The extensions of the environment with the integration of sensing systems in any space, in conjunction with ubiquitous computing are enabling the so-called Smart Space Sensor Networks. This new generation of networks are offering full connectivity with any object, through the Internet of Things (IoT) and/or the Web, i.e., the Web of Things. These connectivity capabilities are making it feasible to sense the behaviours of people at home and act accordingly. These sensing systems must be integrated within typical elements found at home such as furniture.
