An Approximate Model of Radio Wave Propagation for Inter-Vehicles Communication Simulation Systems
نویسندگان
چکیده
In development of inter-vehicles communication (IVC) systems, simulation technologies are very essential to verify the correctness of protocols. We focus on a model of radio wave propagation for IVC simulation systems and approximate the model. As a land mobile communication model, we adopt Kaji model. In our model, a distance between vehicles, a building density, and an angle between a road and a line-of-sight of two vehicles are used as the approximate parameters instead of detailed information of buildings. From experimental results, our model has 84% accuracy and 17 times computation speed-ups in comparison with the orig-

With the rapid growth of indoor wireless communication systems, the need to accurately model radio wave propagation inside the building environments has increased. Many site-specific methods have been proposed for modeling indoor radio channels. Among these methods, the ray tracing algorithm and the finite-difference time domain (FDTD) method are the most popular ones. The ray tracing approach ...

This paper proposes a vehicle-to-vehicle propagation model implemented with SDL. To estimate the channel characteristics for Inter-Vehicle communication, we first define a predicted propagation pathloss between the moving vehicles under three typical scenarios. A Ray-tracing method is used for the simple gamma model performance. Keywords—Inter-vehicle communication (IVC), propagation model, roa...
