In this paper, an empirical propagation model for indoor corridor at 5 GHz based on ray tracing dataset has been proposed. The model can predict the line-of-sight (LOS) and non-line-of-sight (NLOS) path loss characteristics for indoor corridor with T-junction using distances from the junction to the transmitter and receiver, while taking into account the width of the corridor.
Current propagation models used in network simulations neglect obstacles of a propagation environment and employ over-simplified assumptions that the received signal strength is a simple function of distance and the transmission area of a node is circular. These assumptions are in contradiction with the actual tests and the measurement results. To run reasonable simulations for evaluating the performance...
Next-generation mobile networks will offer wireless coverage through heterogeneous radio accesses. The possibility of realistically simulating advanced mobility scenarios in such networks, with the users roaming across different radio technologies, depends on the availability of light models capable of predicting the users' mobility and the wireless coverage offered by the heterogeneous infrastructure...
This paper presents a new model based on the geometrical-optical theory and the uniform theory of diffraction (GO-UTD) for predicting the characteristic of RF propagation in rectangular tunnel. It transforms three-dimensional (3D) propagation model of radio signal in tunnel to two-dimensional (2D) propagation model, which could be easily tackled. Simulation results compared with another prediction...
This article introduces a novel distributed simulation system for diverse simulation tasks of communications systems. With the help of its parallel distributed structure and outstanding computing power, many computationally expensive simulations can be completed in an acceptable duration. Moveover, its cooperative infrastructure is suitable for simulation tasks in multiuser scenarios or other tasks...
