Research on VANETs (vehicular ad hoc networks) date back to the beginning of the 2000s. The possibility of enabling communication between vehicles through a wireless network stimulated the creation of new protocols, devices, and diverse utilization scenarios. Due to the intrinsic difficulties of using a real testbed to evaluate these research contributions, several simulators were developed at the time. Recently, with the advent of autonomous vehicles and the emergence of novel technologies (e.g., 5G and edge computing), new research challenges on VANETs are coming into sight. Therefore, revisiting VANET simulators is required to identify if they are still capable of evaluating these new scenarios. This paper presents an updated review of VANET simulators, showing their current state and capabilities to assess novel scenarios in VANET research. Based on this analysis, we identify open research challenges that should be addressed in current and future VANET simulators.

VANET模拟器：更新后的评论

VANET（车载自组织网络）的研究可以追溯到2000年代初。通过无线网络实现车辆之间通信的可能性刺激了新协议，设备和各种使用场景的创建。由于使用真正的试验台来评估这些研究成果存在固有的困难，因此当时开发了一些模拟器。近年来，随着自动驾驶汽车的出现和新技术（例如5G和边缘计算）的出现，对VANET的新研究挑战已经浮出水面。因此，需要重新访问VANET仿真器，以识别它们是否仍然能够评估这些新方案。本文介绍了VANET模拟器的最新评论，显示了它们的现状和评估VANET研究中新场景的能力。
