Software-Defined Small Cell-Linked Vehicular Networks: Architecture and Evaluation

Vehicle-to-everything services are in the implementation phase, and automakers agree that V2X would improve safety-critical applications already deployed. 3GPP Release 12 introduces LTE-V for V2V V2I services. The is extended to C-V2X support V2N. Because of challenge high mobility system, cutting-edge technologies, such as SDN small cell 5G networks, pave way next generation vehicular networks. a network technology concept divides data control planes. OpenFlow protocol used communication between layer SDN. Different from wireless traditional cellular base stations, cells lower-power sites deployed every few blocks. Small can transmit using mid- high-band spectrums. cell-linked road side unit (RSU) considered key enabling because it has capability create logical cluster platform residing at edge network, which provides computation performance. Accordingly, we consider novel distributed software-defined architecture (diSRsVN). Based on diSRsVN, on-board vehicle, topology discovery over diSRsVN presented. proposed evaluated under an omnet++ simulator. simulation results show effectiveness architecture, improves packet delivery ratio minimizes end-to-end delay.
