Potential Response Mechanism for LoRa Networks Under Jamming Attacks

In the context of the Internet of Things (IoT), an appropriate communication mechanism is crucial to preventing attacks, particularly in IoT applications. The inherent constraints of these devices, such as limited duty cycles, reduced energy capacity, or the inability to listen before transmitting, increase their susceptibility to interference. Low-power wide-area Networks (LPWANs), particularly LoRa, are increasingly used in IoT due to their long-range and low-power capabilities. However, their decentralized structure and the well-known limitations of IoT devices make them vulnerable to attacks, especially jamming. To address this, we propose a 'mitigation mechanism' to optimize network performance in LoRa communications. We evaluated the mechanism's resilience against reactive jamming attacks in simulated environments, showing a clear improvement in network performance over conventional LoRa schemes.
