论文摘要
IEEE 802.11p是在智能运输系统（ITS）中实现专用短期通信（DSRC）的关键技术之一。车辆通信的主要挑战是要处理大量数据。随着车辆密度和速度的增加，要传输的数据也会增加。我们提出了一项协议，该协议可根据车辆遇到的危险水平减少车辆传输的消息数量。提出的协议测量了车辆间距离作为车辆危险的代表，以确定传输的优先级。我们的结果表明，这种传输的优先级直接减少了发射器的数量，因此在关键指标（即PDR，PDR，吞吐量，延迟，通道繁忙和碰撞的概率）方面会导致更高的性能。
IEEE 802.11p is one of the key technologies that enable Dedicated Short-Range Communications (DSRC) in intelligent transportation system (ITS) for safety on the road. The main challenge in vehicular communication is the large amount of data to be processed. As vehicle density and velocity increases, the data to be transmitted also increases. We proposed a protocol that reduces the number of messages transmitted at a vehicle according to the level of danger that the vehicle experiences. The proposed protocol measures inter-vehicle distance, as the representative of the danger of a vehicle, to determine the priority for transmission. Our results show that this prioritization of transmissions directly reduces the number of transmitters at a time, and hence results in higher performance in terms of key metrics--i.e., PDR, throughput, delay, probabilities of channel busy and collision.
