New MQTT standard enables connectivity in the IoT

The International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) have approved the release of MQTT, a foundational Internet of Things (IoT) standard developed by the OASIS consortium. Version 3.1.1 of MQTT was given the designation 'ISO/IEC 20922'.

MQTT defines an extremely lightweight publish/subscribe messaging transport protocol. Because it requires significantly less bandwidth and is so easy to implement, MQTT is well suited for IoT applications where resources such as battery power and bandwidth are at a premium. The range of MQTT applications continues to grow. In the healthcare sector, practitioners use the protocol to communicate with bio-medical devices such as blood pressure monitors. Oil and gas companies use MQTT to monitor thousands of miles of pipelines. MQTT is emerging as a fundamental enabler for telematics, infotainment, and other connected vehicle applications. MQTT is also becoming increasingly popular for interactive mobile applications.  

Brian Raymor of Microsoft Corp., co-chair of the OASIS MQTT Technical Committee, stated: "Standards such as MQTT are critical in allowing enterprises to connect their assets. ISO and IECís support for MQTT provides validation for the international community, and the ISO/IEC 20922 publication promises to accelerate the pace of adoption even more."

MQTT 3.1.1 was ratified as an OASIS Standard in October 2014 and later submitted to the ISO/IEC JTC 1 Information Technology body. As ISO/IEC 20922, this International Standard will continue to be maintained and advanced by the OASIS MQTT Technical Committee
