IEEE任务组最近批准了802.11p修正案，通过在物理层和MAC层引入多个增强功能，实现车辆网络的高效短程通信。它为控制和最关键的数据分组定义了一个控制频率信道，为不太关键的分组定义了一个或几个服务频率信道。在本文中，我们提出了一个分析模型的802.11p操作的控制频率。它捕获了所有建议的增强功能，这些增强功能对于交换道路安全应用程序生成的数据包非常重要。我们通过不同的模拟场景表明，我们提出的模型能够重现预期的结果。我们认为这项工作是理解基于802. 11p的车载通信性能的重要一步，该模型可用于大场景下的安全应用仿真。
The IEEE Task Group has approved recently the 802.11p amendment to enable efficient short range communications for vehicular networks by introducing multiple enhancements at the physical and MAC layer. It defines a control frequency channel for control and most critical data packets and one or several service frequency channels for less critical packets. In this paper, we propose an analytical model for the 802.11p operations in the control frequency. It captures all suggested enhancements important for exchanging data packets generated by road safety applications. We showed through diverse simulations scenarios that our proposed model is able to reproduce expected results. We consider this work as an important step toward understanding the performance of 802.11p-based vehicular communications and the model can be employed in the simulations of safety applications in large scenarios.
