Reliable Heterogeneous Networks using Optical and Radio Communications for ITS

在这项研究中，提出了一种新的异构网络，使用光无线和无线电通信的智能交通系统。在路车通信中，研究了基于不等功率分配的光无线Turbo码、基于改进伪正交M序列的光高密度通信和分层光广播系统。针对车对车通信中的丢包补偿协议，分析了改进的二进制倒计时方法。此外，一个简单的保护方案的错误数据包或欺骗数据包从恶意用户进行评估。

In this study, a novel heterogeneous network using optical-wireless and radio communications for intelligent transportation systems is proposed. For road-to-vehicle communications, the optical-wireless turbo code using the unequal transmission power allocation scheme, the optical high-density communication using the modified pseudo orthogonal M-sequence, the hierarchical optical broadcast system, are investigated. For the loss packet compensation protocol using vehicle-to-vehicle communications, the modified binary countdown method is analyzed. Moreover, a simple protection scheme for error packets or spoofed packets from malicious users is evaluated.
