MQTT-SN: MQTT for the Internet of Smaller Things

MQTT-SN: MQTT for the Internet of Smaller Things

MQTT found success as a lightweight protocol for transporting messages for everything from home automation to racing cars. But what of the networks of tiny sensors?  Devices that might be deployed in the field for weeks, months, even years with processors so small they cannot access the TCP/IP stack.  MQTT-SN (MQTT for Sensor Networks) is designed for situations where a TCP stack is too big, bytes are at a premium and devices need to go to sleep to preserve battery life; MQTT-SN brings the concepts you love from MQTT down to this smaller world.

Supported by expertise from IBM, dc-squared, u-blox, and others, the MQTT Technical Committee has embarked on an effort to bring the MQTT-SN specification into OASIS, review the protocol, achieve greater alignment with MQTT Version 5.0 and work towards standardisation. This work will provide a solid platform for implementers and integrators to offer and develop services targeting low power sensors while providing simple integration to existing MQTT deployments.

If you're looking for messaging over UDP, LoRa, 6LoWPAN or other non-TCP network layer, come along and learn more about MQTT-SN, the opportunities it offers and why you should get involved.

Wireless sensor manufacturers and solution providers that are using, or are interested in using wide area, low power networks.
