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.

Edge to Cloud Protocols

So far in this book, we have generated data or an event from a device running at the network edge. We have discussed various telecommunication mediums and technologies to move that data from the WPAN, WLAN, and WAN. There are many complexities and subtleties in building and bridging these network connections from non-IP-based PAN networks to IP-based WAN networks. There are also protocol conversions that need to be understood.

Standard protocols are the tools that bind and encapsulate raw data from a sensor and turn it into something meaningful and formatted for the cloud to accept. One of the principal differences between an IoT system and Machine-to-Machine (M2M) system is that M2M may communicate over a WAN to a dedicated server or system with no encapsulated protocol whatsoever. For example, a SCADA industrial automation system may use BACNET or ModBus exclusively for communication from machinery to various control computers. IoT by definition...
