Collision avoidance, one of the most promising applications for vehicular networks, dramatically improves the safety of vehicles that support it. In this article, we investigate how it can be extended to benefit vulnerable users, such as pedestrians and bicyclists, equipped with a smartphone. Owing to the reduced capabilities of smartphones compared to vehicular onboard units (OBUs), traditional distributed approaches are not viable, and multi-access edge computing (MEC) support is needed. Thus, we propose an MECbased collision-avoidance system, discuss its architecture, and evaluate its performance. We find that, thanks to MEC, we are able to extend to vulnerable users the collision avoidance protection traditionally applied to vehicles, without impacting its effectiveness or latency.

面向车辆和弱势用户的基于边缘的防撞：对车辆和弱势用户的好处 基于 MEC 的架构

碰撞避免是车载网络最有前途的应用之一，它极大地提高了支持它的车辆的安全性。在本文中，我们研究如何将其扩展到使配备智能手机的弱势用户（例如行人和骑自行车的人）受益。由于与车载单元 (OBU) 相比，智能手机的功能有所降低，因此传统的分布式方法不可行，需要多接入边缘计算 (MEC) 支持。因此，我们提出了一个基于 MEC 的防碰撞系统，讨论了它的架构，并评估了它的性能。我们发现，多亏了 MEC，我们能够将传统上应用于车辆的防撞保护扩展到易受攻击的用户，而不会影响其有效性或延迟。
