论文摘要
在本文中，我们提出了一个分布式的车辆动态频谱访问（VDSA）框架，用于以排地层运行的车辆。鉴于有执照的频带有可能用于车辆应用，例如5.9 GHz。我们的方法提议将部分内部数据流量的一部分卸载到光谱白空间，以增强车辆连接性以支持公路操作。为了启用VDSA，采用了基于动物行为模型的基于大黄蜂的决策过程，用于提供分布式传输带选择的手段。仿真结果表明，分布式VDSA框架可将领导者数据包接收率提高5％，从而表明其潜力提高了平台内通信的可靠性。
In this paper, we propose a distributed Vehicular Dynamic Spectrum Access (VDSA) framework for vehicles operating in platoon formations. Given the potential for significant congestion in licensed frequency bands for vehicular applications such as 5.9 GHz. Our approach proposes to offload part of the intra-platoon data traffic to spectral white-spaces in order to enhance vehicular connectivity in support of on-road operations. To enable VDSA, a Bumblebee-based decision making process is employed which is based on the behavioral models of animals, is employed to provide a means of distributed transmission band selection. Simulation results show the distributed VDSA framework improves the leader packets reception ratio by 5%, thus indicating its potential to increase in reliability of intra-platoon communications.
