Abstract

The application of wireless VANET technology to accident warning systems is gaining an increasing interest. These systems can significantly increase the safety of daily driving and are based on a technology that is steadily becoming mature. We present an experimental comparison between two effective approaches that cope with realistic scenarios. Both rapidly broadcast alert messages throughout platoons of vehicles, and are based on wireless vehicle-to-vehicle (V2V) communications. However, with one approach an alert message propagates through the farthest relay at each hop, whereas with the other it propagatesusing the farthest spanning relay (i.e., the relay that can retransmit farthest away an alert message). With this study we will see retransmitting through the farthest spanning relay at each hop can improve the performance by a factor of two in terms of propagation delay, in comparison to choosing the farthest relay.
