| Outline of Final Research Achievements |
Wireless LAN has been demanded to meet various communication requirements, including not only high-speed communication but also high reliability, fairness, and so on. With the amendments of the 802.11 standards, wireless LAN has become capable of setting a wider range of communication parameters. However, there are many communication parameters and they are related to each other, the search space becomes huge when their combinations are taken into account. In this study, we propose a method for obtaining information from real communication environments, which is an important technique for selecting communication parameters with the aid of a simulation environment reflecting communications between terminals in a real environment.

本研究では，(1) MAC層情報の取得に関して，キャプチャツールの並列化を行うことで，MAC層情報を高速にシミュレーション環境下に取り込む方式の実現と，(2) 物理層情報をシミュレーション環境下にできるだけ正確に取り込む方式として，無線フレームのプリアンブル部の信号への正確な同期方式を考案した．これらの方式により，実環境での端末間の通信状況から，それをシミュレーション環境内へできるだけ高速に，かつ正確に取り込むことができるようになり，シミュレーション環境と実環境間の整合性の向上が可能となる．
