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 covered a necessary portion of IoT communication. Using IP-based standard communication greatly simplifies design and allows for rapid and easy scaling. Scaling is critical for IoT deployments that reach into thousands or millions of nodes. Using IP-based transport allows for common tools to simply just work. 6LoWPAN and Thread demonstrate standards that can be applied to traditionally non-IP protocols such as 802.15.4. Both protocols allow for IPv6 addressing and mesh networking to massive IoT networks. 802.11 is a significant and extremely successful protocol that forms the basis of the WLAN but can also reach into IoT devices and sensors using 802.11ah or transportation systems using 802.11p. The following table contrasts a non-IP traditional protocol with an IP protocol. Typically, the difference will be in power, speed, and range.

The architect needs to balance these parameters to deploy the correct solution:
