Abstract
LoRaWAN is an open networking protocol used to create long-range communication for low-powered devices. LoRaWAN allows the configuration of several parameters that affect the network performance. LoRaWAN end devices utilize this protocol for communication in the Internet Of Things (IoT). These devices transmit and receive data through radio gateways using LoRa RF Modulation. LoRaWAN end devices include Class A, B, and C operational categories that vary based on their functionality in communication with the network. Research has been undertaken on Class A end devices, but a notable gap exists in studies dedicated to Class B and Class C devices. Understanding the communication behaviors of these devices is important for finely tuned and efficient implementations. This study aims to bridge this gap by performing a simulation-based performance analysis in ns-3 for these device classes. Additionally, we demonstrate the potential for significant performance improvements through the careful adjustments of system parameters.
