Abstract (in Japanese) (See Japanese page) 
(in English) Nowadays, the wireless local-area network (WLAN) has become common in the low-cost Internet
access solution using wireless communications between access points (APs) and hosts. In WLAN, traffic demands from users will fluctuate according to day and time. To minimize the power consumption of active APs,
we have studied the elastic WLAN system and implemented the testbed using Raspberry Pi for the AP. The
active AP configuration algorithm has been proposed to optimize the active AP configuration with channel
assignments and host associations for the elastic WLAN system. In this study, we propose the transmission
power minimization extension in the active AP configuration algorithm to further minimize the power consumption. After the active AP configuration is found assuming the maximum power by the previous algorithm, it
minimizes the transmission power of each active AP such that it satisfies the minimum throughput constraint.
The effectiveness of the proposal is verified through simulations using the WIMNET simulator and experiments
using the testbed in practical network scenarios.
