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.

Summary

This chapter has provided foundation material to understand the theory and limitations of wireless communication. More information and deeper study are encouraged to understand the second and third order constraints of data transport. The architect should understand different models and constraints of wireless signals, RF energy dispersion, range, and the fundamental limits of information theory provided by Shannon-Hartley theorem. The architect should also understand the frequency space governance and allocation strategy. This chapter also provides a dialogue and vernacular that will be reused in the upcoming chapters on WPAN, WLAN, and WAN.

The next chapter will start the journey of IoT data from the sensor to the cloud on its first hop across a near-range personal area network. We build up from there to WLAN and WAN systems.
