  1. The Study of Ad Hoc Network アドホックネットワークの研究

  2. Ad Hoc Network for Mobile Phone System Base Station Out of Coverage Ad Hoc Network Coverage area

  3. Ad Hoc Mobile Phone Network (1hop) Base Station • Outside of the range Coverage Area Call birth

  4. Ad Hoc Mobile Phone Network (2hop) Coverage Area Base Station Call birth

  5. Ad Hoc Mobile Phone Network (2hop) Coverage Area Base Station Call birth

  6. Call Birth E F G D R ・ RREQをユニキャスト B C H I A :RREQ Mapping Virtual Map Model ・ マップ上で近い端末同士をグルーピング ・ 推奨受信電力距離だけ離れている端末を依頼端末に決定する Desired received power distance Grouping

  7. バーチャルマップモデル結果 バーチャルマップ_AODV比較 RREQと近隣端末検索パケット総数の推移
