車々間通信プロトコルを活用する代表システムとして車の衝突防止の警告を行うシステムがある。特に交差点周辺では事故が多いと報告され,有効な警告システムが期待される。そのようなシステムは確実かつタイムリーに交差点周辺の情報を取得することを要求している。本稿は筆者らが提案している車々間通信プロトコルと既存プロトコルの振舞いを考察するため,計算機シミュレーションによる性能評価を行い,提案しているプロトコルの有効性を示した。 |

Collision Warning Systems (CWS) can help reduce the probability and severity of car accidents by providing some sort of appropriate warning to the driver through Inter-Vehicle Communication (IVC). Especially, the CWS can help avoid collision at intersections where traffic accidents are frequent. A vehicle equipped with the CWS periodically broadcasts its information, and the CWS on other vehicles use the received information to alert drivers, helping them become aware of the existence of other vehicles. To avoid collision, the CWS has concrete objectives of IVC, i.e., the CWS should receive useful information accurately and in time. To realize CWS, relay control protocols for the IVC have been proposed to provide indirect communications through packet relaying by other vehicles. This paper studies distance-based packet relay through realistic simulated networks. To carry out realistic experiments, we follow the simulation methodology and use performance metrics introduced in previous work. The simulation studies show that the distance-based packet relay protocol achieves higher reception rate and shorter delay; therefore it is a good candidate of IVC protocol for CWS. |
