| 摘 要： | IEEE802.11p协议标准主要用于车载网络通信,有利于推动智能交通系统的实现,因此在实际交通环境下对IEEE802.1 1p协议进行研究具有重要意义.通过修改OpenWrt路由操作系统的ath5k网卡驱动实现了IEEE802.11p协议标准,并移植到Mikrotik RouterBoard433AH路由开发板上成功运行.在此基础上,对实际道路环境下IEEE802.11p协议和IEEE802.11a协议的发送速率、丢包率等网络性能参数进行了研究测量比较.实验数据显示在多障碍物、情况复杂的实际道路环境,IEEE802.11p协议更能满足通信可靠性和有效性的要求.

| Abstract: | IEEE802.11p protocol standard is mainly used in the communication of vehicular network, and would be helpful to construct intelligent transportation system, then it has great significance to study IEEE802.11p protocol in real transportation environment. By modifying ath5k network card driver of OpenWrt router operating system to realize the standard of IEEE802.11p protocol, and transplant it to Mikrotik RouterBoard 433AH to run successfully. On the base of this, measuring and comparing the network performance parameters such as transmitting rate and packet loss rate of IEEE802.11p protocol and IEEE802.11a protocol in real road environment. The experiment data demonstrates that IEEE802.11p protocol has much more reliability and effectiveness in real road environment with many obstacles and complex conditions. |
