3.5 MQTT

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 Publish-Subscribe messaging pattern requires a message broker. The broker is
responsible for distributing messages to interested clients based on the topic of a
message. Now the MQTT Version 3.1.1 becomes an OASIS standard, it is an ideal
protocol for communicating with connected devices in the emerging
"machine-to-machine" (M2M) and "Internet of Things" applications, and for mobile
applications where bandwidth and battery power are at a premium.
