Vehicle-­to Vehicle Communications in Mixed Passenger-Freight Convoys

Vehicle convoys (platoons) hold a promise for significant efficiency improvements of freight and passenger transportation through better system integration. Through the use of advanced driver assistance, vehicles in a convoy can keep shorter distances from each other, thus decreasing energy consumption and traffic jams. However, reliable and low-latency communications are a vital prerequisite for such systems. The standard for vehicle-to-vehicle (V2V) wireless communications is Institute of Electrical and Electronics Engineers (IEEE) 802.11p, and its performance for communication between passenger cars has been wisely explored. However, there are hardly an results about the performance of such systems when both trucks and passenger cars are present. To remedy this situation, the authors propose in this project to first perform extensive measurements of the propagation channel (pathloss and dispersion) between cars and trucks, and between cars whose connection is blocked by trucks. The authors then will use these data as the input of a system simulator, which will tell us not only the probability of successful communication between vehicles, but also analyze robust methods such as multi-hop to resolve the situations where direct communications are not successful.
