论文摘要

The Internet(IoT)环境将不同的智能设备连接在一起,并在连接的设备之间启用无缝数据通信。连接的车辆(CVS)是物联网的主要例子之一,CVS的有效,可靠且安全的操作需要可靠的无线通信系统,这可以确保高吞吐量和低通信延迟。 5G毫米波(5G mmwave)无线通信网络提供了这样的好处,这可能是CV应用程序的推动者,尤其是对于CV数量较高的密集城市地区。在这项研究中,我们提出了一个基于模拟的评估框架,用于CV应用程序的端到端5G MMWave通信。此外,我们将5G MMWAVE与CV应用程序的专用短距离通信(DSRC)技术进行了比较。模拟框架是使用两个模拟器,一个网络模拟器和一个流量模拟器开发的。为了在这项研究中开发框架,我们使用了网络模拟器3(NS-3)和Sumo(开源微观的道路交通模拟器)。我们已经使用端到端的延迟,数据包丢失和吞吐量作为绩效评估指标。我们发现,与DSRC相比,对于密集的城市地区,5G mmwave可以实现更高的吞吐量,较低的延迟和较低的数据丢失。 5G mmwave可以支持在下行链路数据流上具有高通量要求的CV应用程序。通过进一步研究,我们发现5G MMWAVE的性能受到CVS的穿透水平,最大CV速度和CV应用要求的显着影响。

The internet-of-things (IoT) environment connects different intelligent devices together and enables seamless data communication between the connected devices. Connected vehicles (CVs) are one of the primary example of the IoT, and the efficient, reliable, and safe operation of CVs demands a reliable wireless communication system, which can ensure high throughput and low communication latency. The 5G millimeter wave (5G mmWave) wireless communication network offers such benefits, which can be the enabler of CV applications, especially for dense urban areas with high number of CVs. In this study, we present a simulation-based evaluation framework of end-to-end 5G mmWave communication for CV applications. In addition, we compare the 5G mmWave with the Dedicated Short Range Communication (DSRC) technology for a CV application. The simulation framework is developed using two simulators, a network simulator and a traffic simulator. In order to develop the framework in this study, we have used Network Simulator 3 (ns-3) and SUMO, an open-source microscopic roadway traffic simulator. We have used end-to-end latency, packet loss and throughput as the performance evaluation metrics. We have found that for dense urban areas, 5G mmWave can achieve higher throughput, lower latency and lower data loss compared to DSRC. 5G mmWave can support CV applications with high throughput requirement on the downlink data flow. Through further investigation, we have found that the performance of 5G mmWave is significantly impacted by the penetration level of CVs, maximum CV speed, and CV application requirements.
