Abstract
Buildings are important elements of cities for VANETs, since these obstacles
may attenuate communications between vehicles. Consequently, the impact of buildings has
to be considered as part of the attenuation model in VANET simulations of urban scenarios.
However, the more elaborated the model, the more information needs to be processed during
the simulation, which implies longer processing times. This complexity in simulations is
not always worth it, because simplified channel models occasionally offer very accurate
results. We compare three approaches to model the impact of buildings in the channel model
of simulated VANETs in two urban scenarios. The simulation results for our evaluation
scenarios of a traffic-efficiency application indicate that modeling the influence of buildings
in urban areas as the total absence of communication between vehicles gives similar results
to modeling such influence in a more realistic fashion and could be considered a conservative
bound in the performance metrics.
