1 - A Mechanism for Detecting and Identifying DoS attack in VANET

By the other hand this type of network is very sensible to safety problem. This paper focuses on a new mechanism for DoS (denial of service) attacks on the physical and MAC layers in IEEE standard 802.11p. In this proposed solution, DoS attack is detected and iden- tified by using the values of packet delivery ratio (PDR) metric. Simulation results show the acceptable perfor- mance Manuscript profile
