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。
Through the analysis and understanding of 802.11p and WAVE network protocol family of wireless car networking, the paper explores the performance of WAVE network in real equipment and the development method of its application. Based on the real IWCU device built on linux 2.6.32 embedded operating system and integrated with the standard IEEE WAVE protocol suite, the WPSMP format data transmission between the vehicle-mounted unit and the roadside unit under the WAVE standard protocol is programmed. The experimental results under the analysis, the analysis shows that in the short distance range, WAVE communication packet loss rate and delay will increase with distance slowly increased.
