A hybrid framework to prevent VANET from Sybil Attack

The commuter having mobile vehicle attain a widespread safety with the proper use of Vehicular Ad-hoc Network (VANET). Instead of apparent most of the opaque services are raising its hands to adapt safety advancement through VANET. VANETs let road authorities monitor and track vehicles to prevent unsafe driving and provide quick assistance. However, these networks pose architecture, routing, communication, and security challenges as well as these networks are vulnerable to security breaches due to wireless channels. Multiple-identity malicious vehicles threaten the long-term sustainability of networks. VANET is vulnerable to attacks due to lack of infrastructure. One of the most catastrophic attack is Sybil's attack. Sybil vehicles on VANET can spread false information about traffic, an accident, or a roadblock. The driver could be forced to take a route as a result, putting him in risk of an unfortunate event. This paper discusses VANET technology's Sybil-caused limitations. The paper also proposes a hybrid method which is the combination of position-based verification and trust certification method to detect and prevent Sybil attacks.

I. Introduction

Due to recent advancements in communication networks and topologies, Vehicular Ad-hoc Network (VANET) has attracted the attention of scholars and researchers. Passengers' safety might be improved by using VANET, a kind of Mobile Ad-hoc Network that allows automobiles to interact with one another. MANET facilitates communication between fixed, slowly or completely immobile devices [1], [2]. On the other side, the VANET connects and makes it easier for fast moving vehicles to communicate with one another. Vehicles are automobiles that communicate in the vehicular network employing the IEEE 802.11p-based DSRC protocol developed by the North American Standard [3], [4]. Through the use of the VANET, it is possible for vehicles to communicate with one another even in the absence of physical infrastructure. [5].
