Internet of Things-protocol MQTT on the rise

A common language between things is one of the most critical aspects in enabling even the most basic of the “Internet of Things”-visions. MQTT (MQ Telemetry Transport) is rapidly taking gaining momentum as that language.

MQTT is “a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks.”, in other words a language which is suited for allowing things to connect and communicate. MQTT  is not new. It’s been around since 1999, invented  Dr Andy Stanford-Clark of IBM, and Arlen Nipper of Arcom (now Eurotech). For many years, it’s been waiting in the shadows, enabling a few M2M-solutions (machine to machine). But now it seems it’s just about to take off in a major way.

One of the simpler ways of assessing popularity is to use Google Trends which generates a chart based on how often a term is searched for. Below is the chart for “MQTT”.



Another supporting indicator that MQTT is starting to mean more than it did just a couple of years ago is revealed by looking at what other search terms is used in combination with MQTT (android, client, mosquitto…):

Many of the tools, frameworks and APIs that I mentioned in my post “Internet of Things development tools and framework” implement support of MQTT, including Mosquitto which is a message broker (like FedEx, UPS, DHL…) for MQTT.

IBM is investing significantly in MQTT, Facebook uses the protocol in its messaging app and it’s in the process of undergoing standardisation at OASIS. The IBM related investments include support in their MessageSight appliance, reported to be able to manage more than ten million MQTT messages per second coming from a million “things”.

    Nice write-up! I expect that MQTT will gain even more traction after the MQTT 3.1.1 release this year. The MQTT interoperability testing day at EclipseCon this year has shown that several client and broker vendors already support the new generation of that protocol. Very exciting times ahead!

    Oh and you forgot to mention HiveMQ ( in your list of MQTT brokers 😉

    Thanks! Indeed exciting times ahead! I added HiveMQ to the “Internet of Things”-page: Thanks!
