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.

Z-Wave is another mesh technology in the 900 MHz band. It is a WPAN protocol used primarily for consumer and home automation, and about 2,100 products are using the technology. It has found its way into commercial and building segments in the areas of lighting and HVAC control. In terms of market share, however, Z-Wave is not at the market cap like Bluetooth or Zigbee.

Its first manifestation was in 2001 at Zensys, a Danish company developing light control systems. Zensys formed an alliance with Leviton Manufacturing, Danfoss, and Ingersoll-Rand in 2005, formally known as the Z-Wave Alliance. The alliance acquired Sigma Designs in 2008 and Sigma is now the sole provider of Z-Wave hardware modules. Z-Wave Alliance member companies now include SmartThings, Honeywell, Belkin, Bosch, Carrier, ADT, and LG.

Z-Wave is a closed protocol for the most part with limited hardware module manufacturers. The specification is starting to open up more in the public domain...
