TL;DR: A simple shadow fading model targeting system simulations based on real world measurements performed in urban and highway scenarios is presented and a Markov chain based state transition diagram is used to model transitions from LOS to obstructed LOS and an example of state transition intensities for a real traffic mobility model is presented.

TL;DR: In this article, the authors present a shadow fading model targeting system simulations based on real measurements performed in urban and highway scenarios, where the measurement data is separated into three categories, line-of-sight (LOS), obstructed line ofsight (OLOS) by vehicles, and non-line-ofsight due to buildings, with the help of video information recorded during the measurements.

TL;DR: It is found that the diffuse scattering and multibounced nonspecular reflections must be considered for an accurate prediction of the channel in such a rich scattering environment.

TL;DR: It is found that absence of line-of-sight is problematic for system coverage, especially when there are few other significant scattering objects in and around the intersection.

TL;DR: The results show that first-order reflections from a small number of interacting objects can account for a large part of the received signal in the absence of line-of-sight (LOS) in vehicle-to-vehicle channel measurements conducted in three different traffic scenarios.
