Right now, VANET can be implemented in the vehicle such as car and motorbike that use security.
And also VANET also can be implemented inside the GPS system which can make one vehicle and other communicate each other.
But, because of this communication security and safety are the most important things in the development of VANET application.

Several malicious that can make security and safety not good are because of hackers, such as :
1. Curious hacker
