Vehicle Automation Technology
Vehicle-to-everything communication enables autonomous vehicles to communicate with each other as well as neighboring human-driven vehicles and road-side infrastructure. Cellular Vehicle-to-everything (C V2X) communication is proposed in the 3rd Generation Partnership Project release14 standard to address the latency and reliability requirements of cooperative safety applications. Such applications can involve highly congested vehicular scenarios when the network experiences high data loads. Thus, a sophisticated congestion control algorithms 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 feasibility of implementing SAE J2945/1 distributed congestion control on top of the C-V2X stack. Alongside with performance evaluation of transmission rate and range control and resulted improvements on network capacity, recommendations for potential design enhancement are proposed.
