Why MQTT is one of the best network protocols for the Internet of Things

- Sep 30, 2019-

For Internet of Things (IoT) devices, connecting to the internet is a requirement. Connecting to the internet allows the devices to work with each other and with backend services. The underlying network protocol of the internet is TCP/IP. Built on top of the TCP/IP stack, MQTT (Message Queue Telemetry Transport) has become the standard for IoT communications.

MQTT was originally invented and developed by IBM in the late 1990’s. Its original application was to link sensors on oil pipelines with satellites. As its name suggests, it is a messaging protocol that supports asynchronous communication between parties. An asynchronous messaging protocol de-couples the message sender and receiver in both space and time, and hence is scalable in unreliable network environments. Despite its name, it has nothing to do with messaging queues, and uses a publish and subscribe model instead. In late 2014, it officially became an OASIS open standard, and it is supported in popular programming languages by using multiple open source implementations.
