A radio over fiber network architecture for road vehicle communication systems

The road vehicle communication system is an infrastructure network to be deployed along the roads for future intelligent transportation systems. Recently, in order to provide high bandwidth data traffic a radio over fiber based network at millimeter-wave bands has been proposed. In this network a control station is connected to functionally simple base stations via optical fibers. Due to millimeter-wave properties the cell size is very small; therefore, the system is characterized by small cell and high mobility. As a result, it is obvious that mobility management becomes very significant. In this paper we propose a medium access control scheme featuring fast handover and dynamic bandwidth allocation using the ability of centralized control of radio over fiber networks.
