Overview of this book

Develop the skills essential for building Internet of Things solutions with this indispensable guide. In an era where industries heavily rely on IoT, this book will quickly familiarize you with its foundations, widespread use, implementation guided by best practices, and the crucial technologies that allow it to work effectively. Starting with the use of IoT in real-life scenarios, this book offers comprehensive insights into basic IoT hardware, protocols, and technologies. You’ll then learn about architecting and implementing solutions such as wireless sensor networks, cloud computing with AWS, and crucial security considerations. You’ll understand how these systems are operated and monitored over time and work with simple to complex, industry-grade systems, adhering to best practices. In later chapters, you’ll be apprised of future IoT trends and strategies to manage the risks and opportunities that come with them. You’ll also get to grips with a diverse set of tools, including hardware such as ESP32 and Raspberry Pi, and software such as Mosquitto and ChatGPT for generative AI capabilities. By the end of this IoT book, you’ll be able to independently build and design complex, industry-standard solutions fully aligned with best practices.

Integrating application protocols into the design

Now that we’ve seen the considerations of choosing an application protocol, let’s look at integrating the protocols into the design of a network. We already have the knowledge of the components of an IoT network and have seen the interactions that take place between several protocols, so we can put that knowledge to use with the following set of use cases, and see how we can apply our understanding to building our own networks for our use cases based on best practices.

A simple integration into the smart thermostat network

Let’s return to our smart home example, starting off with a simple example of a smart thermostat’s communications with an MQTT broker, which we can see implemented as follows:

In this network, we can see that the Thermostat would publish its measurement of the temperature in the...
