车载网络模拟器比较研究

Comparative Study of Simulators for Vehicular Networks

Rida Saghir, Thenuka Karunathilake, Anna Förster

AI总结:

针对VANET真实实验成本高、仿真器需兼顾真实性与资源效率的问题,本文从资源利用、数据包交付和计算时间三方面比较评估多款车载网络模拟器。

摘要:

车载自组织网络(VANETs)由通过无线链路连接以交换数据的车辆组成。VANETs已成为智能城市中智能交通系统(ITS)的骨干,并通过车对车(V2V)和车对基础设施(V2I)通信支持许多关键服务,如道路安全、交通管理、车队编队行驶等。在任何形式的研究中,测试和评估都起着至关重要的作用。然而,在VANETs中,真实世界实验需要高额投入和大量资源,并可能造成许多实际困难。因此,仿真已变得至关重要,并成为评估VANETs应用的主要方式。此外,首要挑战是真实地捕捉随情境变化的VANETs联网机制。若干因素可能有助于成功实现随机而真实的联网行为。然而,最大的依赖在于用于实现的强大工具,该工具或许能够考虑VANET的所有配置参数、损耗因素、移动性方案及其他关键特性,同时在资源投入与结果之间取得良好平衡,给出实用的性能指标。因此,本研究的目标是在VANETs范围内,从资源利用、数据包交付和计算时间方面评估若干模拟器。

英文摘要:

Vehicular Adhoc networks (VANETs) are composed of vehicles connected with wireless links to exchange data. VANETs have become the backbone of the Intelligent Transportation Systems (ITS) in smart cities and enable many essential services like roadside safety, traffic management, platooning, etc with vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. In any form of research testing and evaluation plays a crucial role. However, in VANETs, real-world experiments require high investment, and heavy resources and can cause many practical difficulties. Therefore, simulations have become critical and the primary way of evaluating VANETs' applications. Furthermore, the upfront challenge is the realistic capture of the networking mechanism of VANETs, which varies from situation to situation. Several factors may contribute to the successful achievement of a random realistic networking behavior. However, the biggest dependency is a powerful tool for the implementation, which could probably take into account all the configuration parameters, loss factors, mobility schemes, and other key features of a VANET, yet give out practical performance metrics with a good trade-off between investment of resources and the results. Hence, the aim of this research is to evaluate some simulators in the scope of VANETs with respect to resource utilization, packet delivery, and computational time.
