Spreading Factor Allocation for Large-Scale Deployment In LoRaWAN Network

Network resource allocation for large-scale terminal node deployment is arousing general interest in LoRaWAN research. And the spreading factor is one of the most important resource parameters in the LoRaWAN network, which affects the data transmission rate, transmission time and distance. Therefore, it is of great significance to improve network performance by constructing a resource allocation scheme to allocate spreading factors to terminal nodes. In order to improve the reliability of the network, this paper proposes a spreading factor allocation method based on LoRaWAN network.
