MQTT

MQTT (Message Queuing Telemetry Transport) is a widely used protocol in IoT (Internet of Things) environments, known for its simplicity and efficiency. Originally developed by IBM in the 1990s, MQTT is designed to handle real-time communication between devices with limited processing power and low network bandwidth. This makes it ideal for IoT applications, such as smart home devices, sensors, and industrial automation systems, where efficient, reliable data transmission is essential.

MQTT uses a publish-subscribe model, where devices publish messages to specific topics on an MQTT broker, and subscribers receive only the messages they’re interested in. This system allows for minimal data transmission, conserving device power and reducing network load. Additionally, MQTT can support quality-of-service levels and persistent sessions, ensuring that data is reliably transmitted even in unstable network conditions. By offering a lightweight communication method with minimal overhead, MQTT has become a cornerstone for IoT and other applications that rely on fast, scalable, and real-time communication between devices and cloud-based applications.
