本文描述了一种用于集成车际通信（IVC）和路对车通信（RVC）的介质访问控制（MAC）协议VRCP（车路侧协同MAC协议）的性能评价，该协议在通信中实现了较高的性能。VRCP不仅可以使用RVC进行IVC的访问控制，还可以使用RVC进行数据通信。利用自主巡航交通模拟器进行了包括MAC模型和阴影模型在内的计算机仿真，以评估VRCP在现实交通条件下的性能。仿真结果显示了VRCP在仅使用RVC进行IVC访问控制和同时使用RVC进行IVC访问控制和数据通信两种情况下的性能。特别是，与传统的IVC争用访问方案相比，VRCP通过RVC补偿IVC的数据，即使在阴影条件下也能获得较高的性能。
This paper describes a performance evaluation of the medium access control (MAC) protocol for integrated inter-vehicle communications (IVC) and road to vehicle communications (RVC) called VRCP (vehicle and road-side collaborative MAC protocol) that achieve the high performance in communications. VRCP can use RVC not only for the access control of IVC but also for the data communication. Computer simulations by the autonomous cruising traffic simulator including the MAC model and shadowing model are carried out to evaluate the performance of the VRCP in realistic traffic conditions. Results of the simulations show the performances of the VRCP in the case of using RVC only for access control of IVC and another case of using RVC for both access control of IVC and data communication. In particular, the VRCP can achieve high performance by using RVC to compensate the data of IVC even in the shadowing conditions, compared to the conventional IVC by contention access scheme.
