Abstract

LoRaWAN and RS-LoRa are two of the most recent MAC layer proposals for Internet of Things (IoT). In this paper, we extend the performance evaluation of these protocols to mobile scenarios, using relevant metrics as the average Packet Error Ratio (PER) and the average network delay. Different scenarios are evaluated by varying the number of gateways, nodes and the traffic load of the end devices. We also propose a pseudocode to represent the Adaptive Data Rate (ADR) mechanism implemented by the LoRaWAN end devices. Our pseudo-code, in addition to making a more illustrative representation of how the ADR mechanism works, facilitates its comparison with potential proposals to improve the performance of LoRaWAN.
