摘　　要：对专为车载自组网设计的应用层文件传输协议VDTP的设计需求进行简单介绍,使用交通仿真软件VanetMobiSim搭建单向双车道和双向双车道的高速公路应用仿真场景,并使用网络仿真软件NS-2就已建的应用仿真场景对VDTP协议进行网络仿真。通过仿真中得到的丢包率和数据传送率等性能指标对VDTP进行评价,从而得出相关结论。Gives a brief introduction of the design requirem ents and implementation theory of the VDTP,which is a file transfer protocol dedicated for vehicular application level, uses the traffic simulator VanetMobiSim to model the simulation context of uni-directional with two lanes and bi-directional with two lanes highway segments, besides, combining the network simulator NS-2 to realize VDTP protocol according to the above application context. Based on the performance index of packet loss ration and data transfer, evaluates the performance of the VDTP, thus gets some conclusions.
