Mastering Internet of Things

By: Peter Waher

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. Mastering Internet of Things starts by presenting IoT fundamentals and the smart city. You will learn the important technologies and protocols that are used for the Internet of Things, their features, corresponding security implications, and practical examples on how to use them. This book focuses on creating applications and services for the Internet of Things. Further, you will learn to create applications and services for the Internet of Things. You will be discover various interesting projects and understand how to publish sensor data, control devices, and react to asynchronous events using the XMPP protocol. The book also introduces chat, to interact with your devices. You will learn how to automate your tasks by using Internet of Things Service Platforms as the base for an application. You will understand the subject of privacy, requirements they should be familiar with, and how to avoid violating any of the important new regulations being introduced. At the end of the book, you will have mastered creating open, interoperable and secure networks of things, protecting the privacy and integrity of your users and their information.

Getting to a better place

Regardless of whether you want it or not, if you're designing something for the Internet of Things, you must lay the foundation for it at the beginning. At the core of the foundation lies communication (among other things). Throughout the chapters, we've seen that protocols such as MQTT and HTTP, while they are easy to use, form a very bad foundation for interconnected things on the internet. While there are applications where they can be used, such as secondary web interfaces (HTTP) and local distributions of data (MQTT), for interoperability and exchange of data between devices on the internet, they are poor options. The amount of vulnerabilities you need to protect against, as well as the lack of communication pattern support, greatly outweighs using another protocol. CoAP with LWM2M might be a good choice, but only if the topology remains fixed, and if data collection and centralized processing is your main (or only) mode of communication. It's also a very poor...
