论文摘要
在本文中，我们研究了数据库支持的车辆动态频谱访问（VDSA）的概念。正如各种研究人员表明，专门用于智能运输系统的5.9 GHz乐队可能会遭受频道拥塞的困扰，我们建议在主动数据库系统的指导下将部分流量的一部分转移到白空间。在我们的工作中，我们描述了我们的测量活动，该活动为专用无线电环境图的人群提供了数据。创建地图后，它将用于VDSA的三种提出的算法中：一种最佳和两种务实的方法。
In this paper, we investigate the concept of database supported Vehicular Dynamic Spectrum Access (VDSA) for platooning. As various researchers show that the 5.9 GHz band, devoted for Intelligent Transportation Systems, may suffer from congestion of the channel, we propose to offload part of this traffic to white-spaces with the guidance of the active database system. In our work, we describe our measurement campaign which delivered data for population of the dedicated radio environment map. Once the map is created, it was used in three proposed algorithms for VDSA: an optimal and two pragmatic approaches.
