| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The COVID-19 Contact-Confirming Application (COCOA) confirms the contact history with infected persons by the identifier broadcast by the smartphone. In this paper, we propose two indoor localization algorithms using contact information. In the indoor facility, pedestrian-carried devices and multiple fixed-positioned anchor nodes broadcast their identifier to the surroundings and periodically send the identifiers that are recognized as close based on the received signal strength from the surrounding device to the server. The server used the number of hops in the proximity relationship between the collected devices to estimate the pedestrian's position. We showed the result of evaluating the localization accuracy of the proposed method by simulation. | |
