The authors is introducing his project as below.

This tutorial will create a skeleton application that can publish and subscribe to messages. You will need to download the requisite libraries, create an MQTT account, insert the appropriate MQTT information into your Arduino sketch, set your MQTT broker, and finally subscribe to the MQTT messages.

Hardware

• Arduino UNO or Arduino Leonardo, Ethernet Shield, 3G/GPRS Shield

Software

• Arduino IDE v. 1.0.5

Libraries

• Pubsub from Knollear
• tlemetry
• timer library v. 1.2

You can get all source code and all detail about the project from below link.
