In Vehicular Ad-hoc Networks, security is a important issue. In the past years, several approaches have been proposed for solving Sybil attack. In this paper a novel scheme to detect the Sybil nodes is presented. The proposed scheme utilizes unmodifiable physical measurements of beacon messages. To increase the detection accuracy, traffic flow theory and safety guard distance is introduced in. The simulation results show 97% detection rate of Sybil nodes, with only about 2% error rate and low overhead.
