Abstract :
The hybrid method combined with 2D ray tracing and simple 3D geometry considerations has generated an efficient and comprehensive propagation modeling for a general propagation environment with buildings, vehicles, and trees. We have investigated the effects of vehicles and groups of trees. Attenuation due to shadowing from vehicle and transmission from groups of trees are significant. The simulation results are presented.
