Cross-layer Data Transmission Control Based on Active Notify of Vehicular Ad-hoc Network Node
车用自组网节点主动通告跨层数据传输控制

To enhance the QoS of data service in vehicular Ad-hoc network, we improved the data transmission control mechanism on technology of Wireless Access in Vehicular Environment(WAVE) and proposed a cross-layer data transmission control scheme based on Active Notify of vehicular Ad-hoc network node(Active Notify EDCA, AN-EDCA).Simulation results indicate, AN-EDCA cross layer data transmission control mechanism efficiently enhances the throughput and guarantees the QoS of data service in vehicular Ad-hoc network.
