Communication protocols for the Internet of Things (IoT) have been optimised to meet the specific requirements of this fast-growing domain. They have been adapted mainly to optimise power consumption, maximise coverage area and facilitate their implementation. One of these protocols is LoRaWAN, which uses the ADR algorithm (Adaptive Data Rate) and aims to reduce power consumption by reducing data rate and transmission power. The ADR algorithm has been specifically optimised for static systems,

... hat is, systems where devices do not move or have limited mobility. In this article, we introduce COMMA (Communication Optimisation Mechanism for Mobility Adaptation), an adaptive data rate mechanism optimised for everyday mobility of devices and people. We use COMMA in telemedicine, our area of expertise, to develop a medical remotemonitoring platform for mobile patients suffering from chronic diseases.
