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.

Edge routers, bridges, and gateways play an integral role in IoT development. The functionality provided by an edge router allows enterprise-level security, routing, resiliency, and quality of service. The bridge/gateway plays an important role in translating non-IP networks into the IP-based protocols necessary for Internet and cloud connectivity. It is also important to realize that the growth of IoT to billions of nodes will take shape with low-cost and constrained electronics. Features such as enterprise routing, tunneling, and VPNs require significant hardware and processing capabilities, and it makes sense to use routers and gateways for that service function. Later in this book, we will also look at how edge routers play a vital role in edge processing and fog computing.

The next chapter will go deep into IoT-based protocols such as MQTT and CoAP, with working examples. These protocols are the lightweight language of IoT and more often than not use gateways and...
