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.

WPAN with IP – 6LoWPAN

In an effort to bring IP addressability to the smallest and most resource-constrained devices, the concept of 6LoWPAN was formed in 2005. A working group formalized the design in the IETF under the specification RFC 4944 (request for comment) and later updated with RFC 6282 to address header compression and RFC 6775 for neighbor discovery. The consortium is closed; however, the standard is open for anyone to use and implement.

6LoWPAN is an acronym that stands for IPV6 over Low-Power Wireless Personal Area Networks. The intent is for IP networking over low-power RF communication systems for devices that are power and space constrained and do not need high-bandwidth networking services. The protocol can be used with other WPAN communications such as 802.15.4, as well as Bluetooth, sub-1 GHz RF protocols, and power-line controller (PLC). The principal advantage of 6LoWPAN is that the simplest of sensors can have IP addressability and act as...
