In this study, the video transmission performances of Wi-Fi and WiMAX technologies are
compared by using simulations. The integration of NS2 and EvalVid defined in the literature
is the simulation tool used in this work. WiMAX and EvalVid packets are patched in to NS2.
A real video file is converted into mp4 format with preprocessing, then its transmission is
simulated over NS2-EvalVid tool for both technologies. The PSNR values obtained by
conducting post processing are compared. The simulations reveal that WiMAX shows better
results than those of Wi-Fi in terms of the PSNR for the video transmission. The main reason
is the improved quality of service features of WiMAX technology.
Key Words: NS2, EvalVid, Video transmission, Wi-Fi, WiMAX
