What is MQTT?
MQTT is one of the most commonly used protocols in IoT projects. It stands for Message Queuing Telemetry Transport. In addition, it is designed as a lightweight messaging protocol that uses publish/subscribe operations to exchange data between clients and the server. Furthermore, its small size, low power usage, minimized data packets and ease of implementation make the protocol ideal of the “machine-to-machine” or “Internet of Things” world.
Why MQTT?
MQTT has unique features you can hardly find in other protocols, like:
Lightweight protocol
it’s easy to implement in software and fast in data transmission.
Based on a messaging technique
You know how fast your messenger/WhatsApp message delivery is. Likewise, the MQTT protocol.
Low power usage
As a result, it saves the connected device’s battery.
How MQTT works?
Like any other internet protocol, MQTT is based on clients and a server. Likewise, the server is the guy who is responsible for handling the client’s requests of receiving or sending data between each other.
MQTT server is called a broker and the clients are simply the connected devices.So:
When a device (a client) wants to send data to the broker, we call this operation a “publish”.
When a device (a client) wants to receive data from the broker, we call this operation a “subscribe”.
In addition, These clients are publishing and subscribing to topics. So, the broker here is the one that handles the publishing/subscribing actions to the target topics.
MQTT Technology Stats & Facts
- It’s a lightweight protocol. So, it’s easy to implement in software and fast in data transmission.
- It’s based on a messaging technique. Of course, you know how fast your messenger/WhatsApp message delivery is. Likewise, the MQTT protocol.
- Minimized data packets. Hence, low network usage.
- Low power usage. As a result, it saves the connected device’s battery.
- It’s real time! That’s is specifically what makes it perfect for IoT applications.
