Vehicular Ad hoc Networks (
) are a special kind of Mobile Ad-Hoc Networks (
) adapted to the communications between vehicles. Several specific protocols to
s have been developed to improve performances and satisfy vehicular application needs. To evaluate a protocol for
, some realistic mobility models are needed. Unfortunately, such models are not provided by Opnet Modeler. In this work, we propose a framework that enhances Opnet Modeler simulation scenario using realistic vehicular mobility models. This framework makes use of the open source software called “Simulation of Urban MObility” (
) and the “input trajectory files” feature of Opnet Modeler.
