    • ユーザの分布が時空間上で非均質な無線ネットワークにおけるリアルタイム制御法の研究
      木村 達明
      2019年度は,時空間上に非均質にユーザが分布するネットワークのリアルタイム制御法の確立に向け,(1)一般の無線ネットワークにおける通信品質の時空間的特性の解析(2)車両間通信の理論的な性能解析(3)空間的に非均質なネットワークの効率的な制御法の基礎検討,をそれぞれ行い,国際会議や論文誌での発表を行った. (1)初年度である2019年度では,まず一般の無線ネットワークにおける無線伝搬環境そのものとユーザの通信品質の時空間的な関係を理論的に解析した.具体的には,数学的な複雑さから考慮されていなかったシャドウイングの空間相関を無線ネットワークモデルに取り入れ,従来明らかではなかった,端末のモビリティやシャドウイングの空間相関が時空間的に通信品質へ与える影響を,簡単な公式により表現することに成功した.さらに,ユーザの配置の空間的な相関がそれに与える影響についても検討を進めており,現在論文を執筆中である. (2)本研究の有用な応用先として車両間通信を考え,いくつかのシナリオにおける理論的な性能評価を行った.例えば,交差点における車両間通信の混雑の影響を評価し,ブロードキャスト通信を理論的に最適化する手法の提案を行った.また,既存の基地局網が車両通信をアシストするセルラ協調型の車々間通信の性能評価も行った. (3)空間的に非均質なネットワークに対するリアルタイム制御法の基礎検討として,近年注目されている,Unmanned Aerial Vehicle (UAV) を空中基地局として用いるネットワークに注目し,その効率的な制御法の検討を行った.具体的には,空間上に非均質に分布するユーザに対して,その通信品質が最大化されるような空中基地局の3次元空間上の最適配置を,従来の集中制御アプローチとは異なり,分散制御による効率的な手法を開発した., 日本学術振興会, 科学研究費助成事業 若手研究, 2019/04 -2022/03, 若手研究, 大阪大学
