摘　　要：基于5G通信技术的车联网面临高速率、低时延、高可靠性和大量流媒体数据分发等需求,提出了一种基于LTE D2D的车联网通信架构,设计基于运动一致性的车辆分簇算法,有效增加持续D2D通信时间,提高通信可靠性;其次,针对簇内车辆的流媒体数据分发,提出一种带时延约束的D2D协作中继转发策略,设计最优中继选择算法,大幅提高数据传输速率,提升网络吞吐量。5G based vehicle networks face with the requirements of high data rate, low latency, high reliability and massive multimedia streaming distribution. A LTE D2 D was proposed based vehicle networks communication architecture and then a movement consistency based vehicle clustering algorithm was designed. The results show it increases sustained D2 D communication time and improves the reliability of D2 D communication. Besides, a D2 D cooperative relaying forward strategy under the constraint of latency for distributing multimedia streaming were proposed, which resulted in significant improvement of data transmission rate and network throughput.
