    摘要   The pervasive adoption of IEEE 802.11 radios  in the past decade has made possible for the easy Internet access from a  vehicle, notably drive-thru Internet. However, originally designed for the  static indoor applications, the performance of IEEE 802.11 in the outdoor  vehicular environment is still unclear especially when a large number of  fast-moving users transmitting simultaneously. In this talk, we first introduce  the Vehicular Communications Networks (VANET). We then discuss on the throughput  performance of fundamental IEEE 802.11 DCF (distributed coordination function)  in the in-motion drive-thru Internet scenario. Due to the high mobility and  transient connectivity of vehicles, we show that the DCF MAC should be  adaptively adjusted according to the vehicle velocities. We then describe the  adaptive mechanisms to achieve smooth video delivery to passengers based on the  Interrupted and variable download throughput of  vehicles.
