MQTT
From BC$ MobileTV Wiki
Messaging Queue Telemetry Transport (MQTT) is an M2M "Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium.
