![]() ![]() We evaluate different scenarios against some base configurations to give a firm comparison on how different factors affect the performance of an MQTT system based on Mosquitto, for payload sizes ranging from 512 to 1,048,576 bytes. ![]() Our principal metric is the transmission time, defined as the time it takes a message to pass from one client through the broker to another client, since MQTT uses a publish/subscribe model with a broker. This paper analyzes the performance of one of the most popular ones, named MQTT (Message Queuing Telemetry Transport), focused on Mosquitto, a widely used implementation. Due to the increasing number of IoT devices connected to the Internet, network protocols intended for IoT technology have gained interest. The Internet of Things (IoT) is the term coined to encompass the myriad of devices that have some data processing and transmitting capabilities.
