Abstract: Gcographirbased location routing protocols are widely used in VANETs since vehicles move fast. Vehicles periodically broadcast its current location information, which results in the event that location information is vulnerable to leak. Therefore, the FLPP (false-based location privacy protection)routing protocols were put forward in this paper. In FLPP, it makes use of the false distance between forwarding vehicles and destinations vehicles to build routing,not the real distance. In order to protect the vehicle location information, the timer of vehicle was cleverly set, and at the same time, the pseudonym strategy was used to hidden identity information. The simulation results show that the proposed FLPP has the high data delivery ratio and the position of privacy protection.
