What is MQTT and how it works?

MQTT is a publish/subscribe protocol that allows edge-of-network devices to publish to a broker. Clients connect to this broker, which then mediates communication between the two devices. When another client publishes a message on a subscribed topic, the broker forwards the message to any client that has subscribed.

What is MQTT protocol?

MQTT is a publish-and-subscribe protocol, meaning that instead of communicating with a server, client devices and applications publish and subscribe to topics handled by a broker. MQTT typically uses IP (Internet Protocol) as its transport but can also use other bi-directional transports.

Which MQTT broker is best?

Evaluation

  • Mosquitto. Mosquitto is a really lightweight MQTT broker written in C.
  • RabbitMQ. RabbitMQ is a very popular message broker written in Erlang that has support for MQTT among other protocols through a plugin.
  • EMQ. EMQ is another Erlang based broker which was very promising.
  • VerneMQ.

What language is Mosquitto written in?

C
Description. Mosquitto provides a lightweight server implementation of the MQTT and MQTT-SN protocols, written in C. The reason for writing it in C is to enable the server to run on machines which do not even have capacity for running a JVM.

Can MQTT work without Internet?
