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.

Other protocols

There are many messaging protocols in use or proposed for IoT and M2M deployments. By far the most prevalent are MQTT and CoAP; the next sections explore a few alternatives for specific use cases.


STOMP stands for Simple (or Streaming) Text Message-Oriented Middleware Protocol. It is a text-based protocol designed by Codehaus to operate with message-oriented middleware. A broker developed in one programming language can receive messages from a client written in another. The protocol has similarities to HTTP and operates over TCP. STOMP consists of a frame header and a frame body. The current specification is STOMP 1.2, dated October 22, 2012, and is available under a free license.

STOMP is optimized for human readability, fault-tolerant parsing, and self-described data. It is not efficient over networks and communication protocols when accounting for bits/message (that is not its intended design goal). Anything with limited connectivity...
