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.

Registering our devices

Before we create a controller, we need to update our sensor and actuator projects. They need to search their brokers for available thing registries and register themselves with them. Since the process is the same for both the sensor and the actuator, only changes to the sensor project will be presented here.

A thing registry client is made available in the Waher.Networking.Provisioning NuGet (or the Waher.Networking.Provisioning.UWP NuGet). It ties into the other XMPP libraries presented so far. We begin by defining a variable for it:

private ThingRegistryClient registryClient = null; 

Once the XMPP client establishes a connection, we call a new method called RegisterDevice. We will define this function to be asynchronous:



await this.RegisterDevice(); 

Looping through available components

The first step is to find the thing registry. We assume that it is made available as a component of the same broker that we are connected to. To avoid...
