摘要

随着仿真模型精度的提高,计算量也越来越大。通常,并行和分布式仿真是一种将仿真加速到可接受的运行时的技术。根据仿真模型的不同,并行或分布式仿真的适用性各不相同。这也适用于耦合V2X模拟,其中分布式计算可能有助于大幅提高性能。在这项工作中,我们确定了分布式V2X模拟的机会和可能性。因此,我们描述并评估了一种方法来分发众所周知的并发交互和运行的vein框架的多个实例。这些实例使用基于高级体系结构的混合联合仿真框架进行耦合。随着流量负载的增加,可以测量到更高的加速。

Performance Gains in V2X Experiments Using Distributed Simulation in the Veins Framework
The increasing precision in simulation models leads to a high computational effort. In general, parallel and distributed simulation is one technique to speed up a simulation to an acceptable runtime. Depending on the simulation model, the suitability of a parallel or distributed simulation varies. This applies also to coupled V2X simulations, where distributed computation may help to increase performance drastically. In this work, we identify opportunities and possibilities regarding distributed V2X simulations. Therefore, we describe and evaluate an approach to distribute multiple instances of the well-known Veins framework that are interacting and running concurrently. The instances are coupled using a hybrid co-simulation framework based on the High Level Architecture. With increasing traffic load, a higher speedup can be measured.
