回顾过去的十年，车载自组织网络（VANET）的研究取得了很大的进展。可以看出，车辆通信协议的研究在车辆网络的背景下，通常是基于仿真模型。这种方法有两个主要的先决条件：首先，详细的网络仿真的所有层的通信协议是必要的，提供了各种各样的工具，由网络社区。第二，车辆机动性的逼真模拟，即，需要道路交通的精确建模来估计所涉及的组件的位置和运动。这篇文章的贡献是双重的：首先，提供了一个调查的移动性建模VANET模拟的演变，概述了通常使用的模拟策略。其次，本文研究了道路交通微观模拟和网络模拟的双向耦合的最新进展如何以较低的计算成本产生更真实的结果。总之，本文主张采用这些技术，是公开的，为进一步研究新的通信协议和机制在VANET的研究领域。
Much progress can be observed in the domain of Vehicular Ad Hoc Network (VANET) research looking back at the last decade. It can be seen that studies of vehicular communication protocols in the context of VANETs are typically based on simulation models. This approach has two major prerequisites: First, detailed network simulation of all layers of communication protocols is necessary as provided by a wide variety of tools by the networking community. Secondly, realistic simulation of vehicles' mobility, i.e., an exact modeling of road traffic, is needed to estimate positions and movements of involved components. The contributions of this article are twofold: First, a survey of the evolution of mobility modeling in VANET simulations is provided, outlining the simulation strategies typically used. Secondly, this article investigates how recent advances in bidirectional coupling of road traffic microsimulation and network simulation lead to more realistic results at comparably low computational cost. In conclusion, this article advocates to employ such techniques that are openly available for further studies of new communication protocols and mechanisms in the domain of VANET research.
