Message Queuing Telemetry Transport (MQTT)

Message Queuing Telemetry Transport (MQTT) is a lightweight messaging protocol designed for low-bandwidth, high-latency networks. It's commonly used in Internet of Things (IoT) applications where devices need to communicate efficiently. MQTT operates on a publisher-subscriber model: devices (publishers) send messages to a central server (broker), which then distributes these messages to subscribing devices. This system allows devices to send and receive data with minimal overhead, making it ideal for scenarios where connectivity is limited or data needs to be exchanged frequently and reliably, such as in smart homes or industrial automation.
