IoT and Edge Computing for Architects - Second Edition

By: Perry Lea

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.

Use cases for edge computing

Edge computing offers the ability to bring processing closer to the sources of data. We have explored several traditional use cases so far in this book, but new uses of edge computing have emerged recently. Ambient computing offers the concept of natural computing that blends into an environment, while synthetic sensing offers the ability to aggregate edge-level sensors into a broad environmentally aware system.

Within this book, we have studied different types of sensors that are used on the far edge. Devices like MEMs sensors, thermal sensors, and PIR motion sensors are designed to measure specific traits of the environment like pressure, temperature, or motion. These sensors alone don't have the ability to understand more complex actions within an environment, for example, a stove burner left on or if the coffee has completed brewing. While these tasks can be accomplished simply by adding sensors directly to each appliance, synthetic...
