Abstract (in Japanese) (See Japanese page) 
(in English) In previous studies, SACA (Semi-Active CW Adaption) method has been proposed as media access control using capture effect considering frame collision in Wireless LAN (WLAN) as well as between multiple WLANs.
However, it has been confirmed that the throughput among the terminals in each WLAN becomes unfair when the distance between WLANs is short.
This problem is caused by the fact that the fairness of the transmission opportunity decreases by the control of reusing the successful back-off time and the control of gradually decreasing the contention window (CW) in SACA method.
Therefore, in this paper, we propose a method to limit the number of reusing time of back-off for improving throughput fairness.
We also evaluate the proposed method by simulation in the environment where multiple WLANs are densely placed.
