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.

Introducing concentrators

Up to this point, we've studied relatively simple devices, each fitting neatly into a physical device. But often, you can add value to your physical device, if you divide it into multiple logical devices. A simple example may be our sensor. It senses two different things: ambient light and motion. These two things are independent of each other and could be modeled as individual sensors logically. But running them on different Raspberry Pi would be more expensive and would only make sense if the actual sensors were separated by some distance. For that reason, it is more cost efficient to implement them into one single unit. They share the same Raspberry Pi, operating system, and network connection.

Dividing a device into multiple logical devices permits you to do things you normally would not do with a single device: you can manage and operate them separately on the network. You can also provision them differently and assign different owners to the different logical...
