Abstract:
Vehicular Ad-hoc Networks contribute to the Intelligent
Transportation Systems by providing a set of services related
to traffic, mobility, safe driving, and infotainment applications.
One of the most challenging applications is video delivery, since
it has to deal with several hurdles typically found in wireless
communications, like high node mobility, bandwidth limitations
and high loss rates. In this work, we propose an integrated
simulation framework that will provide a multilayer view of
a particular video delivery session with a bunch of simulation
results at physical (i.e., collisions), MAC (i.e., packet delay),
application (i.e.,%of lost frames), and user levels (i.e., perceptual
video quality). With this tool, we can analyze the performance
of video streaming over vehicular networks with a high level
of detail, giving us the keys to better understand and, as a
consequence, improve video delivery services.
