Geocast is an important forwarding method for vehicular networks. One standard of vehicular communication is ETSI ITS-G5 GeoNetworking. One of the forwarding methods for geocast in this standard is Contention Based Forwarding (CBF). CBF is dependent on a favourable vehicle distribution to forward messages over multiple hops. A method to extend the effective range of vehicles is to use road side infrastructure to help forward messages. We propose a slightly modified CBF algorithm for road side infrastructure to enable infrastructure assisted forwarding for geocast messages, without modifying the CBF algorithm in the vehicles. In this paper we show that such a relatively small modification can significantly increase delivery rates while also reducing wireless load and delivery delays.
