IoT and Edge Computing for Architects - Second Edition

Overview of this book

Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being. An architectural guide is needed if you want to traverse the spectrum of technologies needed to build a successful IoT system, whether that's a single device or millions of IoT devices. IoT and Edge Computing for Architects, Second Edition encompasses the entire spectrum of IoT solutions, from IoT sensors to the cloud. It examines modern sensor systems, focusing on their power and functionality. It also looks at communication theory, paying close attention to near-range PAN, including the new Bluetooth® 5.0 specification and mesh networks. Then, the book explores IP-based communication in LAN and WAN, including 802.11ah, 5G LTE cellular, Sigfox, and LoRaWAN. It also explains edge computing, routing and gateways, and their role in fog computing, as well as the messaging protocols of MQTT 5.0 and CoAP. With the data now in internet form, you'll get an understanding of cloud and fog architectures, including the OpenFog standards. The book wraps up the analytics portion with the application of statistical analysis, complex event processing, and deep learning models. The book then concludes by providing a holistic view of IoT security, cryptography, and shell security in addition to software-defined perimeters and blockchains.

Part 1 – Sensing and power

An IoT transaction starts or ends with an event: a simple motion, a temperature change, perhaps an actuator moving on a lock. Unlike many IT devices in existence, IoT in a large part is about a physical action or event. It responds to affect a real-world attribute. Sometimes this involves considerable data being generated from a single sensor, such as auditory sensing for preventative maintenance of machinery. Other times, it's a single bit of data indicating vital health data from a patient. Whatever the case may be, sensing systems have evolved and made use of Moore's law in scaling to sub-nanometer sizes and significantly reduced costs. Part 1 explores the depths of MEMs, sensing, and other forms of low-cost edge devices from a physical and electrical point of view. The part also details the necessary power and energy systems to drive these edge machines. We can't take power for granted at the edge. Collections of billions of small...
