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.

The IBM WebSphere Message Queue technology was first conceived in 1993 to address problems in independent and non-concurrent distributed systems and help them to securely communicate. A derivative of the WebSphere Message Queue was authored by Andy Stanford-Clark and Arlen Nipper at IBM in 1999 to address the particular constraints of connecting remote oil and gas pipelines over a satellite connection. That protocol became known as MQTT. The goals of this IP-based transport protocol are to:

  • Be simple to implement
  • Provide a form of quality of service
  • Be very lightweight and bandwidth efficient
  • Be data agnostic
  • Have continuous session awareness
  • Address security issues

MQTT provides for these requirements. A way to think of the protocol is best defined by the standard body (, which presents a very well-defined summary of the protocol:

MQTT stands for MQ Telemetry Transport. It is a publish/subscribe...
