• Internet of Things (IoT)
• network of physically connected devices (things)
• devices provide data
• devices can be controlled
• https://en.wikipedia.org/wiki/Internet_of_Things
• MQTT (MQ Telemetry Transport)
• lightweight publish/subscribe
• small footprint
• low bandwidth (minimum size is 2 bytes)
• From http://mqtt.org/
• “MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol”
