Machine Learning Approach for Detecting Location Spoofing in VANET

Abstract
A vehicular ad-hoc network (VANET) consists of moving and stationary vehicles, along with supporting infrastructure, which communicate with each other through a wireless medium. VANETs are an essential component of an Intelligent Transportation System, which aims to reduce road accidents and traffic congestion and provide additional services for drivers in future smart cities. VANET communication is vulnerable to various attacks and cryptographic techniques are used for message integrity and authentication of vehicles in order to ensure security and privacy for vehicular communications. Such approaches have been shown to be effective for outside attacks, where attackers do not have the credentials to participate in the network. However, if there is an inside attacker additional measures are necessary to ensure the correctness of the transmitted data. Position falsification is an attack where the attacker broadcasts a false position, which can lead to increased traffic congestion or even accidents. Therefore, it is imperative to detect such attacks quickly to ensure safety of all participants in the network. Several trust-based models have been proposed for this in the past. This paper proposes a novel and efficient data-centric approach to detect location spoofing, using machine learning algorithms. We have compared our proposed approach with several existing techniques using the VeReMi dataset and shown that its results improved performance in terms of detection accuracy and other key metrics.
