  Vehicular Ad-hoc Networks (VANET) are self-organized, distributed
communication networks built up from moving vehicles where each node is
characterized by variable speed, strict limits of freedom in movement patterns
and a variety of traffic dynamics. In the last few years vehicular traffic is
attracting a growing attention from both industry and research, due to the
importance of the related applications, ranging from traffic control to road
safety. However, less attention has been paid to the modeling of realistic user
mobility through real empirical data that would allow to develop much more
effective communication and networking schemes. The aim of this study is then
twofold: on one hand we derived real mobility patters to be used in a VANET
simulator and on the other hand we simulated the VANET data dissemination
achieved with different broadcast protocols in our real traffic setting.
