| Abstract(in English) | Highly accurate timestamps of device's local time is required in IoT sensor networks. This is because the timestamp information is important for measured data analysis. However, the conventional high-precision time synchronization method generally requires special hardware and hence difficult to implement in small IoT devices. In this paper, we present a high-accuracy clock offset estimation method that achieves a maximum error of 50 ns by software processing using only ToA(Time of Arrival) information obtained by each node in a wireless LAN network. |
