我们提出了一种用于车辆间通信系统的无争用介质访问控制（MAC）协议，该协议可共享信息以改善高速公路上的安全驾驶。在所提出的系统中，无争用媒体访问是通过周期性的单向令牌传输来实现的。令牌包含有关发送/接收阶段的帧信息。虽然令牌是单向中继的，但拥有令牌的车辆可以向上行链路和下行链路发送数据包。令牌发送间隔被设置为在接收车辆处不受到其他发送车辆的干扰。此外，每次令牌传输都会使用和动态分配多个通道，以减少传输等待时间。我们还评估了所提出的协议的最大端到端传输延迟，并阐明所提出的协议可以保证在允许的延迟时间内进行传输。
We propose a contention-free medium access control (MAC) protocol for inter-vehicle communication systems that share information for the improvement of safety drive on the highway. In the proposed system, contention-free medium access is achieved by periodical one-way token transmissions. The token contains the frame information about the transmission/reception phase. While the token is relaid by one-way, the vehicle which has the token can send a packet to both up- and down-link. The token transmission interval is set not to be interfered from other transmit vehicles at a receive vehicle. In addition, multiple channels are used and allocated dynamically for every token transmission to reduce the transmission waiting time. We also evaluate the maximum end-to-end transmission delay of the proposed protocol, and clarify that the proposed protocol can guarantee the transmission within allowable delay time.
