What is MQTT? As official website said:
"MQTT stands for MQ Telemetry Transport. It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks.
The design principles are to minimise network bandwidth and device resource requirements whilst also attempting to ensure reliability and some degree of assurance of delivery.
These principles also turn out to make the protocol ideal of the emerging “machine-to-machine” (M2M) or “Internet of Things” world of connected devices, and for mobile applications where bandwidth and battery power are at a premium."
Where is MQTT in use? As official website said:
"MQTT has been widely implemented across a variety of industries since 1999. A few of the more interesting examples are listed on the projects list."
Here lists useful MQTT reference link:
- MQTT Official Website
- Eclipse M2M Technologies
- Eclipse paho M2M Client Implementation
- Eclipse mihini Lua Runtime
- Eclipse koneki Lua Development Tool
- Eclipse OMA-DM protocol
In IBM Redbook "Building Smarter Planet Solutions with MQTT and IBM WebSphere MQ Telemetry", it refers to that "Instruments + Interconnection + Intelligent Analysis = Smart Planet". See diagram below:

Next, we are going to talk about MQTT application in "Smarter Planet".
Here are our focuses:
- Understand MQTT protocol internal
- Implement specific MQTT client in C/Java/Lua based on Paho
- Integrate Mosquitto with MQTT Client as "Customized Message Push System"
- Porting Mosquitto & Paho to specific Embedded ARM-Linux platform
- Integrate MQTT Client into Windows/iOS/Android/WindowsPhone/Embedded Linux Client
- Deploy from local service to cloud service
