Internet of Things for Architects

By: Perry Lea

Overview of this book

The Internet of Things (IoT) is the fastest growing technology market. Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being. An architectural guide is necessary 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 devices. This book encompasses the entire spectrum of IoT solutions, from sensors to the cloud. We start by examining modern sensor systems and focus on their power and functionality. After that, we dive deep into communication theory, paying close attention to near-range PAN, including the new Bluetooth® 5.0 specification and mesh networks. Then, we explore IP-based communication in LAN and WAN, including 802.11ah, 5G LTE cellular, Sigfox, and LoRaWAN. Next, we cover edge routing and gateways and their role in fog computing, as well as the messaging protocols of MQTT and CoAP. With the data now in internet form, you'll get an understanding of cloud and fog architectures, including the OpenFog standards. We wrap up the analytics portion of the book with the application of statistical analysis, complex event processing, and deep learning models. Finally, we conclude by providing a holistic view of the IoT security stack and the anatomical details of IoT exploits while countering them with software defined perimeters and blockchains.

The IoT Story

Wireless personal area network standards


This section will explore three relevant wireless personal area networks in the IoT space. A good portion of this section will be dedicated to Bluetooth as it provides a significant number of features and has a very deep presence in the IoT ecosphere. Additionally, Bluetooth 5.0 adds many features and abilities not seen before in the Bluetooth specification and provides range, power, speed, and connectivity that make it the strongest WPAN solution for many use cases. Zigbee, Z-Wave, and IEEE 802.15.4-based networks will also be investigated.

It is also helpful to know that the term WPAN is overloaded. Originally, it was to be a literal body and personal area network on a specific individual connected to wearable devices, but it has now extended its meaning.

802.15 standards

Many of the protocols and network models described in this section are based upon or have a foundation in the IEEE 802.15 working groups. The 802.15 group was initially formed to...
