The amount of systems based on Internet of Things (IoT) has grown at an unprecedented rate over the last years and such an expansion tends to continue. As a consequence, billions of devices are expected to be deployed on diverse industries (e.g., healthcare, automotive) during the next decade. Due to its heterogeneity, the communication of IoT devices is a prominent system function and, thus, distinct communication protocols have been proposed for these systems. This paper presents a performance evaluation of IoT communication protocols for the application layer: AMQP, CoAP, and MQTT. Throughput, message size, and packet loss are the adopted metrics and experiments indicate CoAP protocol provides the best results.
