Internet of Things from Scratch

By: Renaldi Gondosubroto

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.

Application protocols and they fit into the picture

We have discussed much about how IoT networks are formed and their considerations as part of different components, including communication protocols, components for the networks, and many more. However, we have not yet discussed one very important component that operates on the application layer: application protocols. Application protocols operate to ensure that data is sent from one device to another, and understanding which protocol to use and when is imperative for designing effective and optimized networks. In this section, we will be discussing the fundamental application protocols that are usually used within different IoT deployments, and what we should consider when we are faced with different use cases.

We will also have some practical exercises within the section to help you understand the process of how communications work between devices that use the protocol. We will then apply this understanding to the more complex...
