MQ Telemetry Transport

This site provides an up-to-date set of links to information on the IBM Web site relating to the
MQ Telemetry Transport (MQTT) and associated technologies, such as MQTT-S, WebSphere MQ,
WebSphere Message Broker, Lotus Expeditor micro broker, and Really Small Message Broker.
We hope you find it useful!

NEW! Really Small Message Broker (aka "nanobroker")

IBM has made an MQTT pub/sub message broker freely available for evaluation on the AlphaWorks web site.
And this one's really special, as it's only 50K of code!
Download RSMB and give it a try!


MQTT-S - MQTT for Sensors

IBM has published the specification for a new telemetry protocol: MQTT-S - MQTT for Sensors - aimed at embedded devices on non-TCP/IP networks, such as Zigbee.

MQTT-S is a publish/subscribe messaging protocol for wireless sensor networks (WSN), with the aim of extending the MQTT protocol beyond the reach of TCP/IP infrastructure for Sensor and Actuator solutions.

The v1.1 protocol specification includes support for "sleeping devices".

MQTT in the news

home automation and Andy's twittering house

Andy Stanford-Clark has a home automation system which runs on IBM WebSphere MQTT technology, including MicroBroker and more recently nanobroker/RSMB.
Here is a collection of links to videos, podcasts, blogs and articles about Andy's automated home.

Say It, Sign It - SiSi

Several of Summer 2007's IBM Extreme Blue projects used MQTT and microbroker as their messaging infrastructure.
A system called SiSi - Say It, Sign It - helps deaf people by converting speech into BSL (British Sign Language), rendered via an MQTT-attached Java avatar!
Here are the SiSi press links.

Location Aware Messaging for Accessiblity - LAMA

In the Summer of 2006, a group of very talented students from UK universities worked on a project using Smart Phones, MQTT, WebSphere Message Brokers, and some rather clever application software, to implement a prototype system for making information available to people in a way that is relevant to their interests and location. This project is code-named "LAMA" - Location-Aware Messaging for Accessibility, and has been quite widely covered in the world's press! LAMA LINKS

Welcome to the Smart Lab!

In January 2005, the University of Southampton unveiled a rather cool e-Science project, monitoring lab experiments in the Chemistry department and displaying a live dashboard on a Java-enabled cellphone, all using MQTT and the IBM broker.

Here are some press releases associated with this project.
