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.

802.15 standards

Many of the protocols and network models described in this chapter are based upon or have a foundation in the IEEE 802.15 working groups. The original 802.15 group was formed to focus on wearable devices and coined the phrase personal area network. The group's work has expanded significantly and now focuses on higher data rate protocols, meter to kilometer ranges, and specialty communications. Over one million devices are shipped each day using some form of 802.15.x protocol.  The following is a list of the various protocols, standards, and specifications that the IEEE maintains and governs:

  • 802.15: WPAN definitions
  • 802.15.1: Original foundation of the Bluetooth PAN
  • 802.15.2: Coexistence specifications for WPAN and WLAN for Bluetooth
  • 802.15.3: High data rate (55 Mbps+) on WPAN for multimedia
    • 802.15.3a: High-speed PHY (physical layer) enhancements
    • 802.15.3b: High-speed MAC enhancements
    • 802...
