Optimized Adaptive Interference-Aware Rate (AIAR) Strategy for LoRaWAN Networks in Co-Channel Interference Environments

The LoRa (Long Range) technique, designed for long-range communication with minimal energy consumption, is ideal for Internet of Things (IoT) deployments. However, LoRa networks operate over free unlicensed bands, making them susceptible to co-channel interference, a significant threat to network performance. This work investigates the impact of cochannel interference on legacy nodes in a LoRaWAN (LoRa for Wide Area Network) IoT deployment, specifically focusing on the disruption of communication between these devices and the network server. The objective is to analyze the impact of this interference on network performance and to explore strategies for optimizing network performance in the presence of such interference. This paper showed that the LoRaWAN standard does not provide any solution to this problem. For this reason, a strategy AIAR for this is provided and tested in this work, showing its effectiveness in the proposed.
