Visible light communication (VLC) has emerged as a potential wireless connectivity solution for infrastructure-to-vehicle networks where street lights can be configured to serve as access points. In this letter, we propose dynamic soft handover algorithm based on coordinated multipoint (CoMP) transmission. The proposed algorithm takes the rate of change in the received power as an input and accordingly revises the handover margin and time-to-trigger value without explicit information of the vehicle velocity. Our simulation results demonstrate that the proposed algorithm outperforms conventional CoMP and hard handover and maintains a stable signal quality regardless of vehicle velocity.

基于 CoMP 的车载 VLC 网络动态切换

可见光通信 (VLC) 已成为基础设施到车辆网络的潜在无线连接解决方​​案，其中路灯可以配置为接入点。在这封信中，我们提出了基于协调多点（CoMP）传输的动态软切换算法。所提出的算法将接收功率的变化率作为输入，并在没有车辆速度的明确信息的情况下相应地修改切换余量和触发时间值。我们的仿真结果表明，所提出的算法优于传统的 CoMP 和硬切换，并且无论车速如何都能保持稳定的信号质量。
