摘要
为了深入探讨车载网络协议IEEE 802.11p的特性,首先对该协议的物理层、媒体控制访问层及其帧结构进行了详细介绍,然后从工作频率、传输速率及最大功耗等方面与其他短距离无线通信技术进行对比分析,最后归纳出车载网络协议IEEE 802.11p作为一项新的协议标准,在车载网络的实际应用中有着区别于其他无线通信技术的特有优势。因此,对该协议的突破性研究,将有助于车载网络技术在智能交通系统领域走向实用,既具有一定的理论意义,又具有重要的应用前景。
In order to further investigate the characteristics of IEEE 802.11p protocol for vehicular networks,first of all,the physical layer,media access control layer and its frame structure are described in detail,and then the working frequency,trans-mission rate and maximum power consumption of the protocol are compared with those of other short distance wireless communi-cation technologies. Finally,as a new protocol standard,IEEE 802.11p protocol for vehicular networks has a unique advantage from other wireless communication technologies. Therefore,the breakthrough research of the protocol will help vehicular network technologies to move towards practical application for sure in the field of intelligent transportation system,and has the theoreti-cal significance and application prospect.
