Analyzing routing protocol performance versus bitrate in vehicular networks

Vehicular Adhoc Networks (VANETs) are becoming very important since they bring many new features to road transportation (e.g., safety, entertainment, location-based services) and can significantly assist passengers and drivers in their journey. To implement the future intelligent transportation systems, routing protocol´s performance must be evaluated. Even though the performance of routing protocols in the field of VANETs has been addressed in the literature previously through simulations, it has almost always been limited to a small number of vehicles with random mobility, which does not reflect reality due to the increasing number of vehicles worldwide. In this paper we evaluate three well-known routing protocols in a real city scenario. We study the impact of changing the bitrate over those protocols.
