Journal ArticleDOI
Bidirectionally Coupled Network and Road Traffic Simulation for Improved IVC Analysis
TL;DR: The hybrid simulation framework Veins (Vehicles in Network Simulation), composed of the network simulator OMNeT++ and the road traffic simulator SUMO, is developed and can advance the state-of-the-art in performance evaluation of IVC and provide means to evaluate developed protocols more accurately.
Proceedings ArticleDOI
A computationally inexpensive empirical model of IEEE 802.11p radio shadowing in urban environments
TL;DR: An empirical model for modeling buildings and their properties to accurately simulate the signal propagation for IEEE 802.11p radio shadowing in urban environments is created and results show a very high accuracy when compared with the measurement results.
Proceedings ArticleDOI
Plexe: A platooning extension for Veins
Michele Segata,Stefan Joerer,Bastian Bloessl,Christoph Sommer,Falko Dressler,Renate Lo Cigno +5 more
TL;DR: P Plexe as discussed by the authors is an Open Source extension to Veins that offers researchers a simulation environment able to run experiments in realistic scenarios, taking into account physics and mechanics of the vehicles, communications and networking impairments, and Inter-Vehicle Communication (IVC) protocol stacks.
Proceedings ArticleDOI
On the applicability of Two-Ray path loss models for vehicular network simulation
TL;DR: It is argued that replacing a simplified with a fully featured Two-Ray Interference model can not only substantially improve the accuracy of simulation results but also allow capturing one notable artifact that becomes immediately visible in field tests, namely strong signal attenuation at short and medium ranges.
Journal ArticleDOI
Traffic information systems: efficient message dissemination via adaptive beaconing
TL;DR: A new message dissemination protocol is proposed, Adaptive Traffic Beacon (ATB), which is fully distributed and uses adaptive beaconing based on two key metrics: message utility and channel quality, which seems to be much more suitable for TIS than flooding-based protocols.
