| 摘 要： | 针对分簇后的车联网大数据量下网关节点的传输瓶颈问题，结合DMAC分簇算法，提出了通过使用方向性天线在簇与簇之间使相距两跳远的簇头直接建立虚拟通信路径的方法。仿真结果表明：与全向通信方式相比，方法使得簇间通信的端到端延迟减少了110ms，网络的吞吐量增加了将近3Mbps。

| Abstract: | Aiming at problem of transmission bottlenecks of the Gateway node in the clustered vehicular Ad Hoc networks where there is a large amount of datas. Combine with DMAC clustering algorithm ,propose a new method that set up virtual communication path between two hops away cluster-head by using directional antenna. The simulation resuhs show that compared with the omni-directional communication mode, the method can effectively reduce 110 ms of the end-to-end delay between two clusters,and increase the network throughput nearly 3 Mbps. |
