The provision of reliable and efficient communication is a key requirement for the deployment of autonomous cars as well as for future Intelligent Transportation Systems (ITSs) in smart cities. Novel communications technologies will have to face highly-complex and extremely dynamic network topologies in a Vehicle-to-Everything (V2X)-context and will require the consideration of mobility information into decision processes for routing, handover and resource allocation. Consequently, researches and developers require simulation tools that are capable of providing realistic representations for both components as well as means for leveraging the convergence of mobility and communication. In this paper, we present a lightweight framework for the simulation of vehicular mobility, which has a communications-oriented perspective by design and is intended to be used in combination with a network simulator. In contrast to existing approaches, it works without requiring Interprocess Communication (IPC) using an integrated approach and is therefore able to reduce the complexity of simulation setups significantly. Since mobility and communication share the same codebase, it is able to model scenarios with a high level of interdependency between those two components. In a proof-of-concept study, we evaluate the proposed simulator in different example scenarios in an Long Term Evolution (LTE)-context using real-world map data.
提供可靠和高效的通信是部署自动驾驶汽车以及智能城市中未来智能交通系统(its)的关键要求。新型通信技术将不得不面对车辆对一切(V2X)环境中高度复杂和极度动态的网络拓扑结构,并且需要在路由、切换和资源分配的决策过程中考虑移动性信息。因此,研究人员和开发人员需要能够为两个组件提供真实表示的仿真工具,以及利用移动性和通信融合的手段。在本文中,我们提出了一个用于车辆移动性模拟的轻量级框架,该框架在设计上具有面向通信的视角,并打算与网络模拟器结合使用。与现有方法相比,它不需要使用集成方法进行进程间通信(IPC),因此能够显着降低模拟设置的复杂性。由于移动性和通信共享相同的代码库,因此可以对这两个组件之间高度相互依赖的场景进行建模。在一项概念验证研究中,我们使用真实世界的地图数据,在长期演进(LTE)环境中的不同示例场景中评估了所提出的模拟器。

Computer simulations and real-world car trials are essential to investigate the performance of Vehicle-to-Everything (V2X) networks. However, simulations are imperfect models of the physical reality and can be trusted only when they indicate agreement with the real-world. On the other hand, trials lack reproducibility and are subject to uncertainties and errors. In this paper, we will illustrate a case study where the interrelationship between trials, simulation, and the reality-of-interest is presented. Results are then compared in a holistic fashion. Our study will describe the procedure followed to macroscopically calibrate a full-stack network simulator to conduct high-fidelity full-stack computer simulations.
计算机模拟和真实世界的汽车试验对于研究车联网(V2X)网络的性能至关重要。然而,模拟是物理现实的不完美模型,只有当它们与现实世界一致时才能被信任。另一方面,试验缺乏可重复性,容易受到不确定性和错误的影响。在本文中,我们将举例说明一个案例研究,其中提出了试验,模拟和兴趣现实之间的相互关系。然后以整体的方式比较结果。我们的研究将描述宏观校准全栈网络模拟器以进行高保真全栈计算机模拟的过程。

Gigabit-per-second connectivity among vehicles is expected to be a key enabling technology for sensor information sharing, in turn, resulting in safer Intelligent Transportation Systems (ITSs). Recently proposed millimeter-wave (mmWave) systems appear to be the only solution capable of meeting the data rate demand imposed by future ITS services. In this poster, we assess the performance of a mmWave device-to-device (D2D) vehicular network by investigating the impact of system and communication parameters on end-users.
