摘　　要：车联网VANETs（vehicular Ad Hoc networks）中车辆的快速移动缩短了路边设施单元RSUs（roadside units）与车辆间RVC（roadside-to-vehicle）通信的连接时间,降低了RVC通信的数据吞吐量。为此提出基于合作式数据传输的RVC通信CDT-RVC（collaborative data transmission in RVC）方案。引入合作通信模式,移动的动态车辆和静态车辆分别建立各自的群,移动车辆与同方向的其余移动车辆组建成群,向静态车辆传输数据,静态车辆再向RSU传输数据。仿真结果表明,CDT-RVC方案有效提高了数据吞吐量。Time of communication between vehicles and RSUs is short,and the throughput of RVC is reduced due to the fast moving of vehicles in the VANETs.Therefore,a collaborative data transmission in RVC（CDT-RVC）scheme was proposed.Collaborative communication model was applied to improve the data throughput.Moving vehicles and parking vehicles were separately grouped together.A moving vehicle cooperated with other moving vehicles in the same group to transmit data to a group of parking vehicles which in turn forwarded data to the roadside unit.A simple performance analysis shows that CDT-RVC scheme achieves higher data throughput.
