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.

High performance IoT endpoints

So far, we have examined simple sensors that simply return information in a binary or analog form that must be sampled. There are, however, IoT devices and sensors that have substantial processing power and performance for the tasks they undertake. Smart sensors include devices such as video cameras and vision systems. Smart sensors can include substantial amounts of processing capacity in the form of high-end processors, digital signal processors, FPGAs, and custom ASICs. In this section, we will explore the details of one form of smart sensor: a vision system.

Vision systems

In contrast with the simple sensors explored earlier, vision systems are much more complex, which results in substantial hardware, optics, and imaging silicon. Vision systems start with a lens that observes a scene. A lens provides focus, but also provides more light saturation to the sensing element. In modern vision systems, one of two types of sensing elements is...
