【摘要】：針對(duì)IEEE 802.11p協(xié)議移動(dòng)性支持的評(píng)估需求,構(gòu)建基于IEEE 802.11p協(xié)議的車聯(lián)網(wǎng)應(yīng)用場(chǎng)景,利用泊松過(guò)程描述車聯(lián)網(wǎng)系統(tǒng)中的車輛到達(dá)模型。基于Veins平臺(tái)搭建仿真場(chǎng)景并對(duì)仿真參數(shù)進(jìn)行設(shè)置,從端到端延遲、丟包率、吞吐量方面測(cè)試并分析車流密度、車輛行駛速度對(duì)IEEE 802.11p性能的影響以及IEEE 802.11p應(yīng)用于車聯(lián)網(wǎng)環(huán)境的適用性。測(cè)試結(jié)果表明,車輛行駛速度對(duì)基于IEEE 802.11p協(xié)議的車聯(lián)網(wǎng)性能影響較大,而車流密度對(duì)其性能影響較小,同時(shí)IEEE 802.11p協(xié)議適用于主動(dòng)道路安全應(yīng)用且有助于提高合作交通效率。
[Abstract]:According to the evaluation requirement of mobility support for IEEE 802.11p protocol, a vehicle networking application scenario based on IEEE 802.11p protocol is constructed, and the vehicle arrival model in the vehicle networking system is described by Poisson process.The simulation scene is built based on Veins platform and the simulation parameters are set up. The traffic density is tested and analyzed from the aspects of end-to-end delay, packet loss rate and throughput.The effect of vehicle speed on the performance of IEEE 802.11p and the applicability of IEEE 802.11p in vehicle networking environment.The test results show that the vehicle speed has a great influence on the performance of the vehicle network based on IEEE 802.11p protocol, while the traffic density has little effect on the performance. Meanwhile, the IEEE 802.11p protocol is suitable for active road safety applications and helps to improve the efficiency of cooperative traffic.
