A Traffic Flow Theory Aided Physical Measurement-Based Sybil Nodes Detection Mechanism in Vehicular Ad-hoc Networks
International Journal of Networked and Distributed Computing（2015）
摘要
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
