Claims (1)
- 通信ネットワーク、好ましくは車両アドホックネットワーク(VANET)における情報配信方法において、前記通信ネットワーク(1)は、自己の地理的位置を認識している複数の通信ノード(N)を有し、配信プロセスは、それらのノードのうちの1つである発信ノード(O)から、情報が配信されるべき関連エリア(RA)内の特定のノードである第1転送ノード(F1)へ、配信されるべき情報を含むユニキャストメッセージを送信することによって開始され、
前記発信ノード(O)から前記第1転送ノード(F1)へ送信された前記メッセージを受信した前記関連エリア(RA)内の他のノード(C1,C2,C3)が、それぞれ転送ノードを選出し、タイマベースのコンテンションプロセスに基づいて、選出した転送ノードへ前記メッセージのユニキャスト再送を実行することを特徴とする、通信ネットワークにおける情報配信方法。
