| Research Abstract |
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.
