摘要

提出了一种将IVC(车间通信)和RVC(路对车通信)协同使用的媒介访问控制协议，称为车对车和路对车协同MAC协议(VRCP)。VRCP通过自适应选择信道分配方法实现无缝通信。换句话说，在RSU(路边单元)不存在的区域，每辆车使用非持久CSMA随机选择的信道进行通信，在RSU存在的区域使用TDMA选择的信道进行通信。通过仿真对VRCP进行了性能评估。结果显示了VRCP的基本特性，VRCP优于非持续性CSMA。

A collaborative MAC protocol for inter-vehicle and road to vehicle communications

A medium access control (MAC) protocol using both IVC (inter-vehicle communications) and RVC (road to vehicle communications) collaboratively, called vehicle to vehicle and road to vehicle collaborative MAC protocol (VRCP), is proposed. VRCP achieves seamless communications by selecting a channel assignment method adaptively. In other words, each vehicle communicates using a channel selected randomly by non-persistent CSMA in the areas where the RSU (road side unit) does not exist, and communicates using a channel selected by TDMA where the RSU exists. The performance evaluations of VRCP are carried out by simulation. The results show the fundamental characteristics of VRCP, and VRCP is superior to a non-persistent CSMA.
