Abstract(in English) | Internet of Things (IoT) become a common term used in society. LPWA technology is attracting attention as one of its elemental technologies. LoRa is one of LPWA communication technologies using unlicensed bands. Since it is possible to build a self-managed network with LoRa, many services using LoRa will be scattered in the same area without the entire administrator. As a result, communication performance of LoRa may be degraded due to unintended radio interferences. In this research, we propose a method for estimating the network state by successive estimation using Bayesian update and a wireless channel assignment method based on the estimation results. Through computer simulation, we show the network performance improvement with out proposal. |
