Abstract

The Internet of Things (IoT) comprises many heterogeneous devices connected to the Internet. Considering the requirements inherent to the scalability of these systems, the use of efficient communication protocols is essential. The Publish/Subscribe (P/S) communication paradigm has low complexity and reduced control overhead. In the P/S model, the source (publisher) sends messages to a broker, which, in turn, forwards them to interested customers (subscribers). This work presents a comparative analysis between the MQTT protocol and its MQTT-SN variant, both based on the P/S model. The first is considered one of the most used protocols in developing IoT applications, and the second is a variant of the first designed for sensor networks. The results allow us to identify the challenges faced by each of the protocols in the face of a growing number of clients and message flow.
