Using the Right Two-Ray Model ? A Measurement-based Evaluation of PHY Models in VANETs

  title={Using the Right Two-Ray Model ? A Measurement-based Evaluation of PHY Models in VANETs},
  author={Christoph Sommer and Falko Dressler},
We discuss the feasibility of simplified Two-Ray Ground path loss models, which are frequently used in simulationbased performance evaluation of Inter-Vehicle Communication (IVC) protocols. We first show that these models are of no benefit compared to the basic Freespace model. As an alternative, we propose a more exact Two-Ray Interference model. We substantiate this claim based on an extensive set of measurements on the road. We demonstrate that this model substantially improves the accuracy… Expand
On the applicability of Two-Ray path loss models for vehicular network simulation
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.

A statistical channel model for realistic simulation in VANET
A statistical channel model for VANET simulation based on the observation of data from real-world experiments, obtained from an IEEE 802.11p / WAVE compliant testbed is proposed and validated against a set of measurements from an independent research group, proving to be effective and general.

Highway propagation modeling in VANETS and its impact on performance evaluation
This paper proposes a propagation model for V2V communication on highways which reflects conditions found in reality sufficiently well to be applicable for VANET simulation studies and examines the impact of different propagation modeling approaches on the resulting communication performance for varying network loads.

Realistic and Efficient Channel Modeling for Vehicular Networks
A model is developed that accounts for vehicles as three-dimensional obstacles and takes into account their impact on the line of sight obstruction, received signal power, packet reception rate, and message reachability, and it successfully captures both small-scale and large-scale propagation effects in different environments.

Measurement-based evaluation of interference in Vehicular Ad-Hoc Networks at urban intersections
An abstraction approach is introduced based on a configuration of a single vehicle as a set of vehicles in order to diminish the logistic issue as well as the complexity caused by the synchronization of measurement runs on the impact of co-channel interference on the performance of vehicle-to-vehicle communication.

An IEEE 802.11p empirical performance model for Cooperative Systems applications
This model uses data from extensive field trials to infer the correlation between speed, distance and performance metrics such as maximum range, latency and frame loss, and improves this model to limit the number of profiles that have to be generated when there are more than a few couples of emitter-receptor in a given location.
