| Abstract(in English) | A lot of Wireless LAN (WLAN) systems are densely used in conference rooms and cafes by widespread of a mobile access point (AP) and smart phone with tethering function. In this situation, duplicate (same) channels are often used in 2.4Ghz band due to limited bandwidth. In addition, the adjacent channels which interfere other channels are also used. And then, if the WLAN uses the channel affected by adjacent channels easily, the throughput of the WLAN can be decreased. As a result, it is possible that the fairness of WLANs decreases. Therefore, this study proposes a switching method of media access control (MAC) in order to improve the throughput fairness under adjacent channel interference environment. The proposed method tries to apply a modified MAC method for densely environment to the WLAN which throughput is decreased appropriately. From simulation results, it is found that the proposed method can improve the throughput fairness. Therefore, we confirmed the effectiveness of our method in adjacent channel interference environment. |
