Abstract (in Japanese) (See Japanese page) 
(in English) Nowadays, the use of wireless local area network (WLAN) stations (STAs) such as smartphones, mobile routers, and laptop PCs is rapidly spreading. Almost all of these WLAN STAs employs carrier sense multiple access with collision avoidance (CSMA/CA). All STAs suffer critical degradation in communication quality where many WLAN STAs are clustered. This is because the number of collisions of data frames increase in proportion to the number of STAs due to CSMA/CA operation. Besides, CSMA/CA is designed in such a way that STAs try to transmit data frames consecutively if they have any data frames in their transmission queue. This foments the increase of collisions in a congested situation of WLAN STAs. This paper proposes the method that enables to decrease collision probability in a congested situation of WLAN STAs. The proposed method refrains consecutive transmission for a certain period if previous transmission succeeded. Computer simulations verified that the proposed method can improve system throughput characteristics in a congested situation of WLAN STAs. Moreover, a system throughput characteristic against offered traffic load was verified. The proposed method is able to obtain up to approximately 40% higher system throughput characteristic where the traffic load is saturated.
