Abstract： In order to have better research on routing protocols of vehicular networks under NS2，the performance difference between different routing protocol was analyzed，MOVE was used to build real simulation scenarios and simulator scripts were exported into NS2 for vehicular networks simulation. Real experimental datas were received by a simulation experiment and GPSR was compared with AODV，DSDV and DSR，the packet delivery rate，end-to-end delay and route overhead under different node numbers were used as the performance metric to evaluate those routing protocols. The results indicate that GPSR has less delay and routing overhead in real scenarios，has a better overall performance in vehicular networks than other traditional routing protocols，it performs a better stability when the nodes increase.
