【摘要】通过对 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 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。

【Abstract】Based on intensive study of and WAVE Protocol suite of Wireless , 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 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 munication increase slowly with the increase of distance.
