Abstract:

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 ad hoc Networks 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 also present
the adaptive mechanisms to achieve smooth video delivery to passengers
based on the Interrupted and variable download throughput of vehicles.
