"無線メッシュネットワークでは，伝搬路の状態が時間とともに変化し，これに伴いリンク品質の特徴量も時間変化する．特にMIMO (Multiple-Input Multiple-Output)を用いたMIMOメッシュネットワークでは，微小な伝搬路の変動でも各リンク品質が変化しやすくなる．効率的な運用のためにはネットワーク内のリンク品質を管理者へと分かりやすく伝える必要がある．また，リンク同士の特徴量の時間変化の相関を把握することで，あるリンク品質が劣化した場合に同じように品質が劣化しているリンクを発見することが期待できる．更に，個々のリンク容量や信頼性を把握することで，管理者がネットワーク構造を見直す際の参考にすることが考えられる．本論文では，MIMOメッシュネットワークのテストベッドを用い，リンク品質の時間変化を測定する．そして，測定結果に対して自己組織化マップを適用することで，相関のあるリンクを発見可能であることを示す．更に，この結果を踏まえてリンク品質とリンク同士の相関を実際のネットワーク配置図上で可視化する手法を提案する．",
