蜂窝车对一切（C-V2X）通信已在第三代合作伙伴计划第14版标准中提出，以解决协作安全应用的延迟和可靠性要求。此类应用程序可能涉及高度拥挤的车辆场景，其中网络经历高数据负载。因此，为了维护与安全相关的应用程序所需的网络性能，复杂的拥塞控制解决方案至关重要。借助我们的高保真链路级网络模拟器，我们研究了在C-V2X堆栈之上实现SAE J2945/1标准中指定的分布式拥塞控制算法的可行性。我们描述了我们的实现，并使用相关指标评估传输速率和范围控制机制的性能。此外，我们确定了潜在的设计改进和进一步调查的领域。
Cellular Vehicle-to-everything (C-V2X) communication has been proposed in the 3rd Generation Partnership Project release 14 standard to address the latency and reliability requirements of cooperative safety applications. Such applications can involve highly congested vehicular scenarios where the network experiences high data loads. Thus, a sophisticated congestion control solution is vital in order to maintain the network performance required for safety-related applications. With the aid of our high-fidelity link-level network simulator, we investigate the feasibility of implementing the distributed congestion control algorithm specified in SAE J2945/1 standard on top of the C-V2X stack. We describe our implementation and evaluate the performance of transmission rate and range control mechanisms using relevant metrics. Additionally, we identify areas for potential design enhancements and further investigation.
