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.

Long-Range Communication Systems and Protocols (WAN)

So far, we have discussed wireless personal area networks (WPANs) and wireless local area networks (WLANs). These types of communication bridge the sensors to a local net but not necessarily the Internet or other systems. We need to remember that the IoT ecosphere will include sensors, actuators, cameras, smart-embedded devices, vehicles, and robots in the remotest of places. For the long haul, we need to address the wide area network (WAN).

This chapter covers the various WAN devices and topologies including cellular (4G LTE and 5G standard) as well as other proprietary systems including Long Range (LoRa) radio and Sigfox. While this chapter will cover cellular and long-range communication systems from a data perspective, it will not focus on the analog and voice portions of mobile devices. Long-range communication is usually a service, meaning it has a subscription to a carrier providing cellular tower and infrastructure...
