 note = {本論文では，緊急車両の優先走行を円滑にするための緊急車両接近通知において，交差点でのパケット伝搬を考慮し，受信車両が遭遇推定を用いて中継すべきかを自律的に判断する条件ベースフラッディング手法CB-Floodingを提案する．CB-Floodingでは，通常はGreedy Forwardingにより中継車両を制限し，交差点では交差点近傍の車両が中継をして全道路セグメントにパケットを伝搬させる．加えて，緊急車両の走行経路外でパケットを受信した車両は，周辺の交通状況から緊急車両と遭遇するかを推定し，遭遇する場合のみ中継する．都市部を想定した環境でシミュレーションを行い，CB-Floodingが特に道路が混雑した状況において高いパケット散布率を維持しつつ総パケット送信数を抑えているという結果から，CB-Floodingの有用性を示す．, The approach warning of emergency vehicle is a vehicle-to-vehicle messaging for cooperative driving between emergency vehicle and its surrounding vehicles. It provides emergency vehicle smooth driving through the urban roads by letting the surrounding vehicles stay away from it safely in timely manner. In this paper, we propose CB-Flooding, a condition based flooding method. In our proposal, every receiver decides to forward packets by themselves, according to the situation. In the normal case, vehicles forward packets the same way as Greedy Forwarding. At the intersection, every vehicle forwards packets to all directions. In addition, vehicles which are not in the emergency vehicle's way when they receive a packet, they estimate whether they are going to be on the road where the emergency vehicle plans to drive. Only if vehicles could be possibly in the emergency vehicle's way before emergency vehicle passes, they forward packets. We evaluate CB-Flooding through the computer simulation, assuming the urban traffic and road environment. The results show that the packet arrival rate keeps up a high level, while keeping the total number of packets reasonably low amount.},
