How to route packets efficiently and reliably is an important issue in Vehicular Ad hoc Networks (VANETs). Due to the high mobility of vehicles, the communication topology of vehicles in VANET changes rapidly. In this paper, a Virtual Landmarks-based approach is suggested. Under the assistant of Virtual Landmarks, an efficient path is guaranteed even if the roads topology is complex. Our approach is applicable to routing packets between a vehicle and static destination. Simulation results shows that in comparison with previous work, our approach has much lowest communication cost and guarantees a reliable path.
