Abstract
Vehicular networks provide a variety of data services to vehicles through roadside units (RSUs), and cooperation among multiple RSUs is important to support high mobility of vehicles. However, in conventional vehicular network architectures with independently operating RSUs, coordination of RSUs and mobility support for vehicles are limited as the number of RSUs or vehicles increases. We propose using a vehicular cloud radio access network (vCRAN) with edge computing infrastructure where communication and networking resources are centrally controlled. The proposed vehicular network consists of remote radio heads (RRHs) located at roadsides, mobile edge computing (MEC) servers responsible for signal processing and service management, a cloud server managing MEC servers, and a software-defined network (SDN). This vehicular network provides a mobility support method for seamless inter-Rrhand inter-MEC-server connections for vehicular services.
