摘要:
作为一种典型的VANETs(vehicular ad-hoc networks)通信协议,IEEE 802. 11p采用为低移动性网络设计的DCF作为基本传输机制,因此需要针对IEEE 802. 11p协议对于节点具有高速移动性的VANETs通信场景的适应性进行评估分析。首先基于测试评估的需求,构建了一种典型的VANETs通信场景;其次,考虑VANETs网络特点设定了场景中的信道模型和通信流量模型;然后,基于Veins平台搭建了仿真环境,并对仿真参数进行了配置;最后,以端到端延迟、丢包率和吞吐量作为评价标准,在Veins平台上仿真研究了传输频率、车流密度、车辆速度对IEEE 802. 11p网络性能的影响。仿真结果表明,网络因素和移动性因素共同影响IEEE 802. 11p的延迟性和可靠性;高传输频率不利于提高IEEE 802. 11p的网络性能;车辆速度对基于IEEE 802. 11p性能影响较大,而车流密度对其性能影响较小,并且在低速情况下,车流密度对IEEE802. 11p性能无显著影响。
Abstract:
As a typical communication technology for VANETs，IEEE 802． 11p uses DCF as the basic transport mechanism，which is de- signed for low－mobility networks． Therefore，it is necessary to evaluate and analyze the adaptability of the IEEE 802． 11p to VANETs communication scenarios with high mobility． Firstly，we construct a typical communication scenario for VANETs based on the require- ments of test and evaluation． Secondly，we set the channel model and traffic flow model based on the characteristics of VANETs． Third- ly，we build a simulation environment based on Veins platform and configure the simulation parameters． Finally，we take end to end de- lay，packet loss rate and throughput as the evaluation criteria and study the effects of transmission frequency，traffic density and vehicle speed on the performance of IEEE 802． 11p on the Veins platform． The simulation shows that network and mobility impacts the delay and reliability of IEEE 802． 11p． High transmission frequency do not help to improve the performance of IEEE 802． 11p． Speed has a great influence on performance of the IEEE 802． 11p，while traffic density has little impacts． Traffic density has no significant effect on net- works performance of IEEE 802． 11p in low speed environment．
