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.

Communication theory

The IoT is a conglomeration of many disparate devices autonomously producing and/or consuming data on the very far edge of layers of networks and protocols. It is important to understand the constraints in building communication systems for the IoT or any form of networking. The IoT will combine body area networks, personal area networks, local area networks, and long-range wide area networks into a web of communication channels.

Most of what makes the IoT possible is built around communication fabric; therefore, this chapter is dedicated to reviewing the fundamentals of network and communication systems. We will now focus on communication and signaling systems. We will explore the range, energy, and limitations of communication systems and how the architect will use these tools to develop a successful IoT solution.
