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.
