Provides a detailed analysis of the technologies chosen for and driven by applications of the Internet of Things Wireless Technologies for the Internet of Things: A Layered Approach presents a holistic perspective toward Internet of Things (IoT) from applications to interfaces for home automation, sensor networks, smart grid, and healthcare. The author—a noted expert in the field—examines IoT as a protocol–stack, and details the physical layer of the wireless links, the networks created by the various nodes, and the applications which drive the need for IoT. The text outlines the standards for ZigBee, Bluetooth LE, Z–Wave, Wi–Fi, and Thread and covers the physical layers as a protocol stack including common theory, modulation schemes, access methods, bands, and Bluetooth. The author includes a discussion of authentication and encryption and offers an analysis of the network layer. He introduces mesh networks, controllers and end devices, and covers a variety of topics in the medical industry. The book also presents standards, service models, and communication models for a variety of personal healthcare devices including blood pressure monitors, pulse oximeters, glucose meters, thermometers, weighing scales, independent living activity hubs, and sleep apnea breathing therapy equipment.
