one of the most important routing protocols used in Ad hoc networks is AODV. This protocol is a reactive protocol that searches routes only when they are needed. It always exchanges control packets between neighbor nodes for routing. For reduction of control overheads and bandwidth consumption and make AODV usable for VANET, we have eliminated route discovery phase by restricting neighbor’s distance and number of discovered routes. This restriction leads to reduce most of control overheads. We make an improvement on AODV and propose PAODV as routing protocol. This protocol improves AODV control overheads and makes routes more stable. One of the technical differences between MANET and VANET is mobility model. Manhattan is the mobility model for VANET that we use to evaluate our method.
