Zusammenfassung:PROBLEM TO BE SOLVED: To determine a transmission route for making communication in which a cooperation relay transmission technology and a routing technology are consistent with each other while using the respective advantages, in multi-hop transmission in a radio communication network.SOLUTION: A radio station 10 composing a transmission route of a multi-hop transmission relays a control frame along the transmission route. The radio station 10 to be a relay station and the radio station 10 to be a terminal station, on the basis of a control frame received along the transmission route and a control frame heard with a radio link which is not included in the transmission route, calculate direct transmission and calculates transmission quality of the relay transmission and transmission quality of the cooperation relay transmission recursively. The radio station 10, when the best transmission method is selected on the basis of the calculated transmission quality, re-sets the transmission route with the selected transmission method. The radio station 10, by means of the selected transmission method, performs multi-hop transmission along the re-set transmission route. 【課題】無線通信ネットワークにおけるマルチホップ伝送において、協力中継伝送技術とルーティング技術のそれぞれの利点を生かしながら、互いに整合性を取った通信を行うための伝送ルートを決定する。【解決手段】マルチホップ伝送の伝送ルートを構成する無線局10は、当該伝送ルートに沿って制御フレームをリレーする。中継局となる無線局10、及び終了局となる無線局10は、伝送ルートに沿って受信した制御フレームや、伝送ルートに含まれない無線リンクにより傍聴した制御フレームに基づいて直接伝送を算出するとともに、中継伝送の伝送品質及び協力中継伝送の伝送品質を再帰的に算出する。無線局10は、算出した伝送品質に基づいて最も良い伝送方法を選択すると、選択した伝送方法により伝送ルートを再設定する。無線局10は、選択した伝送方法により、再設定した伝送ルートに沿ってマルチホップ伝送を行う。【選択図】図1
