Vehicle platooning systems improve road active safety while reducing vehicular congestion. Visible light communications (VLC) is an efficient technology that enables safety messages exchange between platoon members, and thus improves road safety. Nevertheless, packet transmission could be perturbed by neighboring vehicles, impacting the quality of service and inducing packet loss. Therefore, it is of paramount importance to tackle the provisioning of a vertical handover, of a group of competing platoon vehicles, to a radio frequency (RF) technology. This paper models the network selection procedure by means of a congestion game with an unknown number of players. More precisely, the game considers players that aim at choosing resources among a certain number of resources. Moreover, the game considers the lack of information about the users’ preferences. The main objective is to distribute platoon vehicles among available RF technologies, while maximizing the throughput of each user and avoiding network congestion. The game is solved with the safety-level equilibrium. Performance analysis shows that our solution offers high throughput, low delay, and packet loss ratio for each platoon vehicle while achieving load balancing among available networks.

车辆排队系统提高了道路主动安全性，同时减少了车辆拥堵。可见光通信 (VLC) 是一种高效技术，可实现排成员之间交换安全信息，从而提高道路安全。然而，数据包传输可能会受到相邻车辆的干扰，影响服务质量并导致数据包丢失。因此，解决一组相互竞争的排车辆向射频 (RF) 技术的垂直切换问题至关重要。本文通过未知数量的参与者的拥塞博弈对网络选择过程进行建模。更准确地说，该游戏考虑旨在从一定数量的资源中选择资源的玩家。而且，游戏考虑了用户偏好信息的缺乏。主要目标是在可用的射频技术之间分配排车，同时最大限度地提高每个用户的吞吐量并避免网络拥塞。该博弈以安全水平均衡解决。性能分析表明，我们的解决方案为每个排车提供了高吞吐量、低延迟和丢包率，同时实现了可用网络之间的负载平衡。
