摘要 通过对802.11p及无线车联网WAVE网络协议族的分析和理解,研究探索真实设备中WAVE网络的性能及其应用程序的开发方法。以构建于linux 2.6.32嵌入式操作系统之上并集成标准IEEE WAVE协议族的真实IWCU设备为平台,编程实现WAVE标准协议下车载单元与路边单元之间进行wsmp格式的数据传输,对记录下的实验结果进行分析,分析表明在短距离范围内,WAVE通信的丢包率和延时会随着距离的增加而缓慢增加。 Based on intensive study of 802.11p and WAVE Protocol suite of Wireless VANET, WAVE Network performance and the development methodology of WAVE application are explored. Based on IWCU platform integrating WAVE Protocol suite and embedded operating system, and with 2.6.32 as its kernel, the formal of wsmp data transmission between roadside unit and onboard unit is achieved through programming. The preliminary analysis of experimental results shows that within a short distance, the packet loss rate and latency in WAVE communication increase slowly with the increase of distance.
