Claims (4)
- セルラー移動無線通信システムで使用される送受信スロットを利用することによって、端末間でアドホック無線通信網を構築して通信を行うアドホック無線通信システムにおけるチャネル設定方法において、
各アドホック網に属する端末が、自端末が属する網以外のアドホック網からの干渉量として受信電力を測定し、当該受信電力が閾値以上であった場合に同じ周波数を利用する他のアドホック網が接近したと判定するアドホック網接近判定ステップと、
前記同じ周波数を利用する他のアドホック網が接近したと判定した場合に、判定したアドホック網に属する端末の中から代表端末を選出する代表端末選出ステップと、
選出された代表端末が、接近した前記他のアドホック網の代表端末との間で通信を行い、どちらのアドホック網がどのスロット区間でアドホック通信を行うかを決めるための処理を行う調停ステップと
を備えたことを特徴とするアドホック無線通信システムにおけるチャネル設定方法。 - 前記代表端末選出ステップは、最も干渉量が多い端末が代表端末となる処理を含むことを特徴とする請求項1記載のアドホック無線通信システムにおけるチャネル設定方法。
- 前記代表端末選出ステップは、前記アドホック網に属するすべての端末が干渉量を共有し、一定の周期ごとに最も干渉量が多い端末に代表端末が移され、代表端末を選出すると判断された時刻に代表権を持つ端末が代表端末となる処理を含むことを特徴とする請求項1記載のアドホック無線通信システムにおけるチャネル設定方法。
- 前記調停ステップを実行した端末が、前記調停ステップを実行後、周囲の他のアドホック網からの干渉量を測定し、前記周囲の他のアドホック網が十分遠くに離れたと判断した場合には、前記周囲の他のアドホック網が用いていたスロットを、自己が属するアドホック網用として利用するステップをさらに設けたことを特徴とする請求項1 記載のアドホック無線通信システムにおけるチャネル設定方法。
