          <datacite:description descriptionType="Other">無線LANの普及によって，無線LANを利用するノードどうしが密集化している．無線LANでは，このような密集環境において同一のチャネル干渉によりスループット性能が低下する．この問題に対して，送信電力（TxP），信号検知閾値（CCAT）を制御することでスループット性能の改善が期待できる．既存制御手法では，TxP，CCATを制御し通信範囲を可能な限り縮小することで，スループット性能を向上させた．しかし，通信相手を基準にした制御を行っており，スループット性能はBSSによって大きく異なり公平性が損なわれている．本論文では，密集無線LANにおけるBSS群内協調によるスループット性能の維持と公平性向上を目的としたリンクアダプテーションをともなった動的送信電力，信号検知閾値制御であるFair Carrier Sensing and Power Control with Link Adaptation（FCPL）を提案する．シミュレーション評価により，既存手法と比較してスループット性能を維持しながら，公平性の向上を示す．</datacite:description>
          <datacite:description descriptionType="Other">Wireless Local Area Networks (WLANs) have been deployed more densely according to high wireless demands. In a wireless LAN, throughput performance decreases due to the co-channel interferences in a dense environment. Transmission power (TxP) control and clear channel assessment threshold (CCAT) control improve the system performance by addressing this problem. Existing TxP and CCAT control methods improve system throughput compared to the legacy system. Throughput fairness among Basic Service Sets (BSSs), however, has not been enough since TxP and CCAT are controlled by cooperating only within a BSS. Furthermore, link adaptation has not been considered, and there is room for further improvement. This thesis proposes Fair Carrier Sensing and Power Control with Link Adaptation (FCPL), which is a dynamic TxP and CCAT control with link adaptation for improving fairness by coordinating among nodes in BSS Groups in dense wireless LAN. In the simulation evaluation, FCPL show improved fairness while maintaining throughput performance compared to existing methods.</datacite:description>
