The 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 the difference from its position. this type of detection need not disclose its identity and privacy is preserved. this is validated by simulating in a realistic test case
