LoRa defines a low-power network based Spreading Factor (SF) configuration, which allows gateways to accommodate hundreds of thousands of devices by adjusting data rates by gateway and device distance. However, the simulation resulted in approximately 46,000 devices. In this paper, we propose a device grouping technique for building LoRa-based Massive IoT networks. The proposed technique is a method of grouping devices by time to reduce the probability of data collision in an environment where hundreds of thousands of LoRa devices are configured. The proposed technique confirmed that LoRaSim simulation can accommodate hundreds of thousands of devices. |
