In this paper, the authors present a survey on the state-of-the-art for Vehicular Ad hoc NETworks (VANETs). They start by reviewing possible applications of VANETs which could be classified into safety and non-safety applications. The authors expose the forces and weaknesses of this class of Mobile Ad hoc Networks. They survey two of their most critical issues which consist on the Quality of Service (QoS) and security. QoS becomes a hot topic due to unique features such as high mobility of the vehicles and the mediocre quality of links between them. Security is another challenging issue since vehicular networks are processing in open environments.
