IEEE Open Journal of Vehicular Technology (OJVT) 是一本开放获取的全电子期刊，发表原创高质量论文，涵盖移动无线电、机动车辆和陆地交通领域电气和电子工程的理论、实验和操作层面。我们的期刊不仅欢迎原创高质量论文，也欢迎以行业为中心的出版物，重点关注研究成果并提出对进行类似研究的人员有用的想法。

我们十二月的第一篇推荐论文由卡尔顿大学、梅德尼耶特大学、蒙特利尔理工学院、加拿大国家研究委员会和 MDA 的作者合作完成。论文主要探讨在自由空间光卫星网络中，网络时延和卫星发射功率之间的取舍：想让通信更快，就需要卫星用更多功率来发射信号。研究还发现，云层天气会明显影响激光上下行通信的稳定性，这说明这类卫星网络对大气条件非常敏感。

当一组低地球轨道（LEO）卫星通过激光卫星间链路（LISL）互相连接时，就形成了自由空间光卫星网络（FSOSN）。在这样的网络中，LISL 的通信距离对整体网络性能影响很大。LISL 距离增加会减少所需链路数量，从而降低网络延迟，但同时也会增加卫星的发射功率。在本文中，我们使用 Starlink 第一阶段第 3 版（最新版本）和 Kuiper 第二层（Kuiper 最大的卫星层）星座，研究了卫星发射功率与网络延迟之间的权衡关系。

研究发现，平均网络延迟（即跨洲连接在所有时间段最短路径的平均延迟）与平均卫星发射功率（即最短路径卫星平均发射功率的平均值）呈反向关系：LISL 距离增加时，平均网络延迟下降，而平均卫星发射功率上升。此外，研究还发现，云层状况会影响激光上下行通信的中断概率，说明 FSOSN 对大气变化非常敏感。

We invite original contributions on, but not limited to:

• VDT architecture and multi-layer modelling
• Communication protocols (5G/6G, C-V2X) for real-time VDTs
• AI and ML for adaptive twin control
• Cybersecurity, quantum-safe VDT communication
• Blockchain and trust management
• Edge/cloud integration
• Use cases (e.g., fleet management, predictive maintenance, autonomous driving)
