MQTT PROTOCOL & WORKING

Glad that I'd the opportunity to learn on MQTT protocol.The insights are shared below in this article.

MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol designed for efficient communication between devices with limited resources, such as embedded systems, IoT devices, and mobile devices. It follows a publish-subscribe messaging pattern, where devices can publish messages to topics, and other devices can subscribe to those topics to receive the messages.

In MQTT, a broker acts as an intermediary between publishers and subscribers. Publishers send messages to the broker, which then forwards them to all subscribers that have expressed interest in the corresponding topic. The broker ensures the delivery of messages to subscribers and manages the subscriptions.

To establish communication in MQTT, devices connect to the broker using the TCP/IP protocol. They can then publish messages to topics or subscribe to topics to receive messages. The messages are typically small and contain data payloads, allowing for efficient transmission and reduced bandwidth usage.

To conclude we can say that, MQTT provides a flexible and efficient messaging solution for applications with low power and limited network bandwidth requirements. Its lightweight nature and support for reliable communication make it suitable for various Internet of Things (IoT) and machine-to-machine (M2M) scenarios.
