This research presents an optimal deployment of resources in a road-side unit (RSU) infrastructure, using heterogeneous communications, for providing efficient coverage to dynamic vehicular networks. We configure scenarios, with a realistic approach, using mobility software tools to verify the behavior of vehicular traffic on the roads. In order to reach efficient coverage in a dynamic vehicular network, we determine the optimal location of the heterogeneous communications infrastructure, employing a novel mathematical approach for modeling the related optimization problem. The dynamic resources assignment is tailored to a real-life scenario by means of a set of restrictions regarding the coverage and the capacity of the heterogeneous communication infrastructure RSU, as well as the restrictions that additionally impose the capacity of the channels to achieve optimal use of the vehicular network.
