Abstract (in Japanese) (See Japanese page) 
(in English) With the widespread adoption of smartphones and tablets and the expansion of IoT services, network traffic in wireless LANs is expected to continue increasing. In high-density environments, in particular, many devices share limited frequency resources, leading to serious issues such as throughput degradation and increased communication latency caused by channel congestion. To address these challenges, IEEE 802.11be, adopted in Wi-Fi 7, introduces Multi-Link Operation(MLO),whichenablessimultaneousmanagementandutilizationofmultiplewirelesslinksacrossdifferent frequencybandsand channels.However, the concurrent use of multiple links in wireless LANs increases the consumption of frequency resources. As a result, conventional fixed channel selection schemes have difficulty adapting to temporally and spatially varying wireless environments, leading to reduced spectrum utilization efficiency due to congestion. To address this issue, this study proposes a method that utilizes a distributed spectrum management database which accumulates and shares information on surrounding wireless communication environments. Based on this information, the proposed method performs channel selection and traffic allocation for each MLO link.
