| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this report, we investigate the QoS estimation accuracy of a passive-monitoring-based frame count method in a large-scale Wi-Fi network. The null function data frame (NFDF) is a fixed-length IEEE 802.11 frame and is periodically emitted from a user equipment. Here, the NFDF-based QoS estimation method has been proposed in the literature. We implemented this method in an access point, and evaluated its performance both in an ideal environment and a large-scale conference. Through the real-world measurements in the ideal environment, we obtained the correlation coefficient of 0.65 between the NFDF retry ratio and the corresponding frame error rate. Furthermore, the correlation coefficient was 0.56 at the large-scale conference, which justified the efficacy of the NFDF counting method. | |
