Vehicular Ad-Hoc Networks are networks of communication between vehicles and roadside units. These networks have the potential to increase safety and provide many services to drivers, but they also present risks to privacy. Researching mechanism to protect privacy requires two key ingredients: a precise definition of privacy that reflects citizens' concern and perceptions, and an upstanding of the type of attacks in VANETs. In this research, the authors formulate a workable definition of privacy, and focus on tracking attacks, which they found to lacking. Although considerable research has been performed in tracking none of the published solutions ensures full protection.
