Many results have been published in the literature based on performance measurements obtained from simulations of Vehicular Ad hoc NETworks (VANETs). These simulations use as input traces of vehicle movements that have been generated by traffic simulators which are based on traffic theory models. To the authors' knowledge, no one has published any work based on actual large-scale recordings of vehicle movements. They use recordings of actual vehicle movements on various roadways. In order to enable analysis on this scale, they have developed a new VANET simulator, which can handle many more vehicles than NS-2. To enable one to use their own simulator, they present results of a cross-validation between NS-2 and their simulator, showing that both simulators produce results that are statistically the same.
