By using position-based routing in VANET, a vehicle makes forwarding decision based on the geographic position of destination and single-hop neighbours. The position of a destination is obtained through location service, while the positions of single-hop neighbours are obtained through neighbour discovery. Location service is a process where a destination sends its location updates towards location server vehicles through hop-by-hop forwarding, and a source obtains this information from such location servers through location query. Neighbour discovery is a process where a vehicle advertises its position to all neighbours within a broadcast range. In many cases, adaptive neighbour discovery schemes are more suitable, but they suffer from high channel load and stale neighbour information.
