Abstract (in Japanese) (See Japanese page) 
(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.
