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.

Discovering things on the internet

When creating a controller that will use devices connected to the internet, you must solve the problem of finding the devices you want to use. You can choose to preconfigure the identities of the devices in a production environment, or to manually configure the identities after installation. These methods require additional effort on the part of the manufacturer, operator, or installer. It would be nice if the things could discover themselves somehow.

In local area networks, discovery is easier. You can use a multi-cast based protocol, such as the Simple Service Discovery Protocol (SSDP), part of Universal Plug and Play (UPnP), to let your devices multi-cast their existence and capabilities in the network. Controllers can listen to these messages, and connect to suitable devices they find. But on the internet, such a method is not feasible for many reasons, and it is difficult to secure.
