The recent advances in wireless communication techniques have made it possible for fast-moving vehicles to download data from the roadside communications infrastructure [e.g., IEEE 802.11b Access Point (AP)], namely, Drive-thru Internet. However, due high mobility, harsh, and intermittent channels, volume of individual vehicle per drive-thru is quite limited, as observed real-world tests. This would severely restrict service quality upper layer applications, such file video streaming. On...
