Federação de brokers do protrocolo MQTT implementação e análise de desempenho

Abstract

The deployment of billions of intelligent devices capable of sensing and interacting with their environment by acquiring and sending data over the network is known as the Internet of Things. Among the protocols that enable the communication of these devices, the most widespread is the Message Queuing Telemetry Transport (MQTT). MQTT uses only one central server (i.e., broker) for filtering and forwarding messages in its standard implementation. The broker presents itself, in this context, as a single point of failure and a possible bottleneck in system performance. Thus arises the need for scalable MQTT approaches, such as clusterization and federation of brokers. The present work aims to analyze the federation’s performance of MQTT brokers. Tothisend,wepresentanewimplementationofafederator: anapplicationthatprovides federation capabilities to brokers. Using the federator, we set up a case study comparing the performance of the traditional (single broker) and federation approaches, using the publication latency as a metric.
