Outline of Research at the Start

異なる無線システムが混在する環境で稠密に配置されたAPを有効に利用する方法について検討する.具体的には,WWW閲覧やメール送受信などの古典的なベストエフォート型サービス(BE)と,動画閲覧などのストリーミングサービスを一定の帯域を保証して提供するサービス(GBR)を想定し,サービスごとに複数の物理AP から構成される仮想AP を形成して,GBRサービスの呼損率を目標値以下に抑えながらBE サービスの満足度を可能な限り向上させる手法を提案する

Outline of Final Research Achievements

In this research, I focused on efficient use of spectrum resources in densey deployed wireless LAN access points (APs). Specifically, I assumed a traditional Best Effort (BE) service such as WWW browsing, e-mail and transferring files, and a streaming service such as video with Guaranteed Bit Rate (GBR). I proposed a method to improve the satisfaction ratio (utility) of BE service users as much as possible while keeping the call blocking probability of GBR service users below the target value by configuration of a virtual AP consisting of multiple physical APs for each service.

Academic Significance and Societal Importance of the Research Achievements

携帯端末の高性能化と無線ネットワークの高速化が続いているが,周波数は有限の資源であり,有線ネットワークにおけるケーブル敷設のような手段で増やすことができないため,その効率的利用は永遠の課題である.本研究では,WWWやメールなどの古典的なサービスだけでなく,動画像などのストリーミングサービスを想定し,同じ量の周波数資源を用いてどこまでユーザの満足度を高められるかを明らかにした.
