          <dc:description>本稿では，基地局が密に設置されているような都市環境において，WiFi チャネルで予想される被干渉の程度を，フレーム監視により得られる各チャネルでのトラフイックと RSSI，ならびに隣接チャネルの使用パターンに基づき相対的に予測する手法を提案する．これにより，各チャネルにおける絶対性能値を推定するのではなく，複数チャネルから相対的に良好なチャネルを選択する．複数のアクセスポイントの干渉が予想される現実的なシナリオを複数用意し，それらを用いてシミュレーション実験を行った結果，チャネル間の相対性能による順位が実測とほぼ一致したことを確認した．</dc:description>
          <dc:description>This paper presents a method to estimate the performance of WLAN systems in urban areas. We consider (i) inter-channel interference and (ii) urban situations. As it is often hard to identify the channel with less interference, we present a channel scoring function that estimates the performance level of each channel. To build the scoring function, we have conducted exhaustive simulations, and multiple regression analysis has been applied where channel occupancy patterns, traffic volumes and RSS in those channels are used as explanatory variables. To evaluate our method, this scoring function was examined with realistic scenarios where several APs interfere with the AP of interest. We have confirmed that the scores and the actual performance are well-matched.</dc:description>
