This book provides an in-depth understanding of Internet of Things (Io T) technology. It highlights several of today’s research and technological challenges of translating the concept of the Io T into a practical, technologically feasible, and business-viable solution. It introduces two novel technologies–sensor-cloud and fog computing–as the crucial enablers for the sensing and compute backbone of the Io T. The book discusses these two key enabling technologies of Io T that include a wide range of practical design issues and the futuristic possibilities and directions involving sensor networks and cloud and fog computing environments towards the realization and support of Io T.Classroom presentations and solutions to end of chapter questions are available to instructors who use the book in their classes.
