During the last few years, continuous progresses in wireless communications have opened new research fields in computer networking, aimed at extending data networks connectivity to environments where wired solutions are impracticable. Among these, vehicular traffic is attracting a growing attention from both academia and industry, due to the amount and importance of the related applications, ranging from road safety to traffic control, up to mobile entertainment. Vehicular Ad-hoc Networks (VANETs) are selforganized networks built up from moving vehicles, and are part of the broader class of Mobile Ad-hoc Networks (MANETs). Because of their peculiar characteristics, VANETs require the definition of specific networking techniques, whose feasibility and performance are usually tested by means of simulation. One of the main challenges posed by VANETs simulations is the faithful characterization of vehicular mobility at both macroscopic and microscopic levels, leading to realistic non-uniform distributions of cars and velocity, and unique connectivity dynamics. Yet, freely distributed tools which are commonly used for academic studies only consider limited vehicular macro-mobility issues, while they pay little or no attention to vehicular micro-mobility and its interaction with the macro-mobility counterpart. Such a simplistic approach can easily raise doubts on the confidence of derived VANETs simulation results. In this paper we first present and describe VanetMobiSim, a freely available generator of realistic vehicular movement traces for telecommunication networks simulators. VanetMobiSim is validated first by illustrating how the interaction between featured macro- and micro-mobility is able to reproduce typical phenomena of vehicular traffic. Then, the traces generated by VanetMobiSim are formally validated against those obtained from CORSIM, a benchmark traffic generator in transportation research.
