MQTT-SN

MQTT-SN (Message Queuing Telemetry Transport for Sensor Networks) is a lightweight messaging protocol designed for wireless sensor networks and other low-power devices. It allows these devices to efficiently send and receive small amounts of data over limited bandwidth connections. MQTT-SN is optimized for battery-operated devices, enabling them to communicate with minimal energy use while maintaining a reliable connection. It's commonly used in applications like smart cities, agriculture, and IoT (Internet of Things), where many devices need to share data quickly and efficiently.
