针对现有VANET网络广播传输协议信道利用率低、易造成信道拥塞等问题,提出在路基设备辅助下的改进协议。利用路基设备进行车辆分簇,将簇内车辆编号加入发送数据帧头,每个车辆节点有选择地进行数据分组接收与发送。仿真结果表明,改进协议可以有效地改善传输过程中的信道使用情况,有效信息传输率可提高20%。Direction Transmission Protocol of the Highway Traffic Information Assisted by Roadside-Infrastructure
Existing VANET network broadcast transmission protocols have low channel utilization
and easily lead to channel congestion and other issues
so improved protocol assisted by roadside- infrastructure was proposed. It used roadside-infrastructure to cluster the vehicle. In the clustering
every sending data frame added the vehicle number to its head and each vehicle node received and transmitted the packets selectively. The results show that the improved protocol is able to improve the transmission channel usage effectively
and the effective information transfer rate is able to be increased by 20%.
