Análise de escalabilidade do protocolo MQTT

Abstract

More and more everyday objects are connecting to the internet. The growth of the Internet of Things (IoT) creates new challenges to the computing area, and along with that the need to use new communication protocols. MQTT is a communication protocol based on the pub- lisher/subscriber paradigm and some factors make it ideal for use in the IoT. In this protocol, the broker acts as an intermediary between publishers and subscribers and plays a crucial role to the system’s operation. Scalability approaches of the MQTT protocol involve clustering of brokers. The present work proposes the construction and analysis of a scalability system of the MQTT protocol through clustering of brokers. In order for the system to be created, open-source code solutions were used. With the intention of getting better results for the analysis of the system’s performance, different environments and scenarios were created. Lastly, a discussion is made based on obtained results.
