| 摘 要： | 基于NCTUns对IEEE 802.11p在车路协同系统中车路通信的适应性进行了仿真,分别构建了一个通用城市平面交叉口和一段快速路仿真环境,研究了车辆数与时延、车辆数与吞吐量、车速与时延、车速与吞吐量之间的关系。得出了在仿真环境下,IEEE 802.11p在车辆数较大,特别是40辆以上时,其时延和吞吐量性能急剧变坏,而车速对时延和吞吐量影响很小的结论。

| Abstract: | In this paper,NCTUns is used to study the adaptability of IEEE 802.11p in vehicle infrastructure communication of IntelliDrive system.First,an at-grade urban intersection and a highway environment are designed.Then,the relationships between the number of vehicles and delay,between the number of vehicles and the throughput,between the speed of vehicles and delay,and between the speed of vehicles and the throughput are analyzed.Finally,the conclusion is drawn that the performance of delay and throughput deter... |
