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.

Supporting an IP layer in a protocol stack does consume resources that could be applied elsewhere. However, there are key benefits in building an IoT system that allows devices to communicate over TCP/IP. We will begin by enumerating these benefits; however, it is the role of the architect to balance the cost of these services and features against the impact on a system.

From an ecosystem point of view, regardless of the protocol used at a sensor level, the sensor data will ultimately be fed into a public, private, or hybrid cloud for analysis, control, or monitoring. Outside of the WPAN, the world is TCP/IP-based, as we see in WLAN and WAN configurations.

IP is the standard form of global communication for various reasons:

  • Ubiquity: IP stacks are provided by nearly every operating system and every medium. IP communication protocols are capable of running on various WPAN systems, cellular, copper wire, fiber-optic, PCI Express, and ...
