VANET (Vehucular Ad hoc Network) is a development of Mobile Ad hoc Network or often called MANET. Topology in VANET can change rapidly because of the movement of node so that topology can change dynamically, besides there is problem interesting enough to be examined at VANET that is connectivity between node. There are several routing protocols on MANET that are applied to VANET one of them is AODV (On-deman Distance Protocol) AODV is a reactive or on-deman protocol, this type of routing will only create a route when the source node needs it. AODV protocol routing is further developed one of them is to become AODV-PNT (Prediction Node Trend), by adding prediction of node tendency can improve performance in determining stable route, based on TWR value (Total Weight of The Route). TWR values pay attention to several mobility factors such as speed, acceleration, direction and links quality between vehicles. In this study, we adopted the TWR calculation formula on AODV-PNT and also added another factor that is the number of neighboring nodes in determining the TWR value. From the trial results, modified AODV-PNT managed to increase the value of packet delivery ratio up to 3.7%. As for the number of routing packets generated in the simulation, the modified AODV-PNT protocol produced 21% more packet routing than the original AODV-PNT protocol and 62.4% less than the original AODV protocol. In this study the modification protocol we call AODV-MNS.
