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.

Communications and Information Theory

There are a significant number of technologies and data paths to move data, and a bulk of the material in this book will investigate the aspects, constraints, and comparisons of communication choices for the architect. The previous chapter detailed sensor architecture and design, and now we must marshal the data to the Internet. This requires an understanding of communications and the limitations of moving data.

We begin the short-range and long-range communications discussion with a review of wireless RF signals and the contributing factors that impact signal quality, limitations, interference, models, bandwidth, and range. There are many PAN/WAN communication protocols to choose from in different bands, and the architect must understand the pros and cons of choosing one radio spectrum over the other.

By the end of this chapter, you should understand the limits of radio communication speed and bandwidth. Whether...
