This paper addresses the problem of sustaining the privacy of a vehicle in a vehicular ad hoc network (VANET). In a VANET, vehicles broadcast information as they move on the road. The location of a vehicle can estimated using localization techniques and its identity can be read from its messages. A link can be established between the physical vehicle through localization and its identity is a threat...
A vehicle can be tracked through its locatable transmission. The broadcast by a source contains its current identity and also allows estimation of its location by a receiver. This possibility of mapping between the physical entity and the estimated location through the communication broadcast is a threat to privacy. The changes in the location due to motion and the alteration in the temporal identifiers...
As a vehicle moves on the road and communicates with other vehicles or road side units, communication identity and physical identity may be linked by estimating its position. This is threat to its privacy. However, as it moves its location changes. This breaks the correlation between the vehicle and its location. The change in location also changes the neighborhood of the vehicle. This change in size...
