Introduction to MQTT protocol for IOT applications.

In my previous blog post, I explained why the widely used application-layer protocol HTTP is not suitable for the IOT applications. There are a number of application-layer protocols developed to serve the purpose of IOT like MQTT, AMQP, CoAP, XMPP, STOMP etc. In this blog post, I will provide an introduction to MQTT protocol, its design, architecture and use-case examples.

Why HTTP is not suitable for IOT applications.

When developing modern web-applications, the most commonly used application layer protocol is HTTP. It is suitable for serving hypermedia resources in a request-response fashion over the internet. However, when it comes to the Internet of things(IOT), it tends to perform poorly mainly because it was designed to be a reliable but heavy-weight protocol for the world-wide-web. In this blog, I want to highlight the issues with HTTP with respect to IOT applications.
