On guaranteed Quality of Service of an Internet of Things integrated with a videoconference

Agnieszka Chodorek, Robert R Chodorek


In this paper, an analysis of Internet of Things (IoT) system, integrated with a videoconferencing system built according to the WebRTC architecture, is presented. Analysis covers Quality of Service (QoS) levels of the MQTT protocol, number of active IoT devices and location of a corresponding WebRTC terminal.
