7758 Sybil Attack Detection Technique for Vanets : a Novel Scheme
نویسنده
چکیده
Vehicle adhoc networks (VANET) are an application of Mobile adhoc networks (MANET). VANET performs management of traffic very well. It also circulates safety information to drivers and passengers in the vehicle. Here, in this paper we have proposed a novel scheme of Sybil attack detection mechanism or algorithm by using which the trajectory path communication among vehicles for identification while still preserving their location details. When a vehicle comes within the communicable area of a road-side unit (RSU), it always demands an authorized message from the RSU as the proof of the appearance time at this RSU. The Sybil defense algorithm detects fake nodes from normal nodes in vehicular communication to avoid congestion.

A Physical Measurement-Based Sybil Nodes Detection Mechanism in VANETs
In traffic safety applications of Vehicular Ad-hoc Networks (VANETs), security is a very important issue. Sybil attack is a particular attack where the attacker illegitimately claims multiple identities. In the past, several approaches have been proposed to solve this problem. They are categorized into PKI-based, infrastructure-based, observer-based, and resourcetesting-based schemes. In this p...

Vehicular Ad Hoc Network (VANET) is a wireless network formed between a collection of vehicles connected through wireless connections. VANETs can help increase the passengers‟ comfort, safety, efficiency and convenience by providing them with information about the ongoing road status and other relevant road information. VANETs, similar to other networks, face numerous security threats. One such...
متن کاملThe Detection of Sybil Attack by Location Based Privacy System
In this system Sybil attack is detected by localization of nodes by using the infrastructures. Privacy and security are the two important issues in VANETs. Sybil attack is an attack that the malicious user pretends to be multiple vehicles. This reduces the load on the DMV by finding the Sybil vehicle. This is done by the help of RSU that determines the location of the suspicious node andfind th...
