论文摘要
蜂窝车辆到所有（C-V2X）技术有望为连接的车辆提供超可靠的低潜伏期通信（URLLC）框架。连接的车辆可以帮助我们改善交通安全，拥塞并减少致命事故。 C-V2X承诺通过异构网络体系结构提供许多功能，诸如信息娱乐，始终在远程信息处理，实时导航等方面，提供了新的连接性和智能级别。 C-V2X利用现有的蜂窝结构，正在替换DSRC/Wave进行车辆通信。仍然需要解决一些挑战，需要在采用有效的公路V2X之前解决C-V2X。在本文中，我们研究了车辆到培训的端到端潜伏期（V2P），该潜伏期要求具有可靠数据包输送比率的超低潜伏期。为了评估LTE-V2P性能，我们使用网络模拟器进行了城市交叉路口方案，其中脆弱的路边用户（VRUS）试图越过街道，并且它们与移动的车辆进行通信。我们评估了给定场景的端到端延迟和吞吐量，并得出结论，使用现有网络体系结构延迟很高。通过利用多边访问计算（MEC）服务器的延迟可以大大减少，因此可以使蜂窝V2P通信可行。
Cellular Vehicle-to-Everything (C-V2X) technology promises to provide ultra-reliable low latency communication (URLLC) framework for connected vehicles. Connected vehicles can help us improve traffic safety, congestion and reduce fatal accidents. C-V2X promises new levels of connectivity and intelligence providing numerous features like infotainment, always-on telematics, real-time navigation, etc. with heterogeneous network architecture. C-V2X leverages existing cellular architecture and is on the way to replace DSRC/WAVE for vehicular communication. There are still some challenges which needs to be tackled before C-V2X can be deployed for efficient on-road V2X. In this paper, we look at end-to-end latency for Vehicle-to-Pedestrian (V2P) which demands ultra low latencies with reliable packet delivery ratio. To evaluate the LTE-V2P performance, we used network simulator for an urban intersection scenario where vulnerable road-side users (VRUs) are trying to cross the street and they communicate with moving vehicles. We evaluated the end-to-end latency and throughput for the given scenario and concluded that with the existing network architecture the latency is high. By utilizing multi-edge access computing (MEC) servers latency can be reduce drastically and hence can be made feasible for cellular V2P communication.
