Abstract:
LoRaWAN stands out as one of the fastest growing Internet of Things access networks, thanks to its extensive coverage and operation within the license-free ISM band. This feature enables individuals to easily establish wireless access for their devices. However, a notable drawback of LoRaWAN is its unregulated channel access, which can lead collisions and data loss. While scheduled MAC approaches theoretically offer a solution to such collisions and aim to enhance the reliability of LoRaWan, their real-world applicability, particularly in scenarios involving multiple gateways, remains unexplored. Consequently, we have devised a slot assignment strategy tailored for LoRaWANs with multiple gateways and demonstrate its effectiveness in large deployments across various cities worldwide. The chromatic number as a graph metric of the communication network can predict its suitability for supporting scheduled MAC operation. Additionally, we have developed a methodology to optimize gateway placement based on slot assignment, thereby reducing the number of gateways needed for a given network.
