With development of wireless communications in the two last decades, new infrastructures have been developed. One of them is the Vehicular Ad hoc Networks (VANETs). They are considered as ad hoc networks with the particularity that the topology is always changed, that make more complicated the resource management and open some beaches in security. Specifically on the Physical and MAC layers that are more vulnerable as they are built on distributed systems and a fluctuating radio channel. Thus, it is not easy to know when transmitted data are not delivered to the destination, if this is due to an attack or to a propagation problem. In this study, we propose a new algorithm DJAVAN (solution of Detecting Jamming Attacks in Vehicle Ad Hoc Networks) to detect a jamming attack in VANETs using the Packet Delivery Ratio (PDR) and with the performance analysis, we determine the threshold that can make the difference between an attack and a poor radio link.
