MQTT-SN (MQTT for Sensor Networks)

MQTT-SN (MQTT for Sensor Networks) is a lightweight messaging protocol designed for communication among small devices and sensors in IoT networks. It simplifies data exchange by reducing overhead, making it suitable for devices with limited power, processing capacity, or network bandwidth. MQTT-SN enables sensors to send and receive messages efficiently over various network types, like Bluetooth or Zigbee, facilitating real-time data sharing and control in smart environments. Its streamlined design helps maintain reliable connections and efficient communication in resource-constrained sensor applications.
