Vehicular Ad Hoc Networks (VANETs)

Inter-vehicular networks are one of the most significant and challenging modern communication systems. Both academia and industry are extremely active in such a prolific area of research, and fundamental advances are expected to happen in the next years. The main reason for the success of vehicular networks as a research area is because the related applications have a direct impact on everyday life. In particular, we can cite safety, entertainment, or driving-assistance applications. Inter-vehicular communications can take place in two basic ways, either in pure ad hoc mode (aka vanet) or with the support of fixed nodes along the route (infrastructure mode). In the ad hoc case, vehicles communicate without any external support. In the infrastructure case, some typically static nodes are deployed along the roads in order to improve both connectivity and service provision. In these research theme we are evaluating the performance of data transfers in inter-vehicular communications. In addition, we are analyzing the behavior of Internet-like protocols in such environment, where nodes have to face not only medium restrictions, but also the highly dynamic mobile scenarios.
