Emulating Vehicular Ad hoc Networks for Evaluation and Testing of Automotive Embedded Systems

Abstract

The evaluation and testing of cooperative applications based on Vehicular Ad hoc Networks (VANETs) in real testbeds is difficult due to the need for repeatable scenarios and largescale experiments. Therefore a novel virtualization-based framework is presented to evaluate automotive software in the context of emulated VANETs. The approach enables the precise and large-scale evaluation of real-world implementations through the synchronized execution of network and vehicle simulators as well as the applications encapsulated in virtual Electronic Control Units. This paper provides a detailed description of the framework's structure and its components as well as an validation of the proposed synchronization algorithm. The performance comparison with pure network simulation indicates that despite additional overhead large-scale experiments can be conducted without loss of accuracy.

Thread-Based Modeling and Analysis in Multi-Core-Based V2X Communication Device

“…Kim et al [36] proposed a method of combining a network and traffic simulator for building a test bed using characteristics of a real road environment such as mobility and a channel model called V2XREF. Schiller et al [37] proposed a virtualization-based framework for emulating vehicular ad hoc networks for evaluating and testing networkaware automotive embedded systems. Choundhury et al [38] proposed an integrated simulation environment for testing V2X protocols and applications that combines three simulators such as a traffic simulator, a network simulator, and an application simulator.…”

“…The conformance testing method tests the protocol conformance for V2X commutation [31][32][33]. The function testing method checks the function of the application for various scenarios to ensure the reliability and efficiency of the V2X application [34][35][36][37][38][39][40][41][42][43]. The performance testing method evaluates whether the latency, reliability, throughput, etc., of the V2X application are guaranteed [44][45][46][47][48][49][50][51][52].…”

A Survey of Vehicle to Everything (V2X) Testing

“…Their emulation framework was also based software simulation and could be used in function testing. Schiller and Alois [65] had presented a new virtualization-based approach for emulating VANET by which application function testing could be performed. Choudhury [66] designed the simulation environment for V2X protocol and application testing.…”
