Ray-tracing for Vehicle-to-vehicle Communications
نویسندگان
چکیده
A comprehensive model of the transmission channel between moving vehicles in realistic environments is presented in this paper. The approach consists of tree major parts: the modelling of the road traffic, the modelling of the environment adjacent to the road and the actual modelling of the wave propagation between the vehicles. A ray-tracing approach is used for the wave propagation, which allows for wide-band as well as narrow-band analyses of the channel. Characteristic time series of impulse responses of the inter-vehicle transmission channel can therefore be calculated for link level simulations. Simulation results are compared to wide-band channel measurements at 5.2GHz, yielding a good agreement.

A Hybrid Channel Model based on WINNER for Vehicle-to-X Application
V2V and V2I channel modeling became recently more of interest. To provide realistic radio channels either expensive measurements or complex ray tracing simulations are mostly used. Stochastic channel models are of low complexity but do not offer that deterministic repeatable realism. Based on the WINNER channel model and a simple single path model, a hybrid model has been developed. The concept...

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...

Vehicular ad hoc Networks (VANETs) enable vehicles to communicate with each other as well as with roadside units (RSUs). Although there is a significant research effort in radio channel modeling focused on vehicle-to-vehicle (V2V), not much work has been done for vehicle-to-infrastructure (V2I) using 3D ray-tracing tools. This work evaluates some important parameters of a V2I wireless channel l...

This paper derives the analytical expression of the temporal autocorrelation function (ACF) of the non-stationary three dimensional (3D) multipath scattering channels, in which scatterers move with constant velocities in random directions around transceivers. The analytical expression involves high dimensional integration within finite interval, thus a methodology based on ray-tracing is propos...
