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.

Zigbee is a WPAN protocol based on the IEEE 802.15.4 foundation targeted for commercial and residential IoT networking that is constrained by cost, power, and space. This section details the Zigbee protocol from a hardware and software point of view. Zigbee got its name from the concept of a bee flying. As a bee flies back and forth between flowers gathering pollen, it resembles a packet flowing through a mesh network – device to device.

Zigbee history

The concept of low-power wireless mesh networking became standard in the 1990s, and the Zigbee Alliance was formed to address this charter in 2002. The Zigbee protocol was conceived after the ratification of IEEE 802.15.4 in 2004. That became the IEEE 802.15.4.-2003 standard on December 14, 2004. Specification 1.0, also known as the Zigbee 2004 Specification, was brought public on June 13, 2005. The history can be profiled as follows:

  • 2005: Zigbee 2004 released
  • 2006: Zigbee 2006 released...
