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.

This chapter has covered the first step in delivering IoT data from devices to the Internet. The first step in connecting billions of devices is using the correct communication medium to reach sensors, objects, and actuators to cause some action. This is the role of the WPAN. We have explored the basis of the unlicensed spectrum and how as an architect we will measure the performance and behavior of a WPAN.

The chapter went deep into the new Bluetooth 5 and Bluetooth 5.1 protocol and compared it to other standards such as the IEEE 802.15.4 basis protocol, Zigbee, and Z-Wave. We explored beaconing, various packet and protocol structures, and mesh architectures. An architect should have an understanding of how these architectures compare and contrast at this point.

The next chapter will explore IP-based PAN and LAN networks such as the ubiquitous 802.11 Wi-Fi network, Thread, and 6LoWPAN, as well as future Wi-Fi communication standards. These networking chapters...
