Performance analysis of video codec (H.263+, H.264) for videoconferencing over wireless local area network (WLAN)
Published 2013“…Therefore, simulations are tested in optimum network (utilizing the bandwidth without any disturbance) and in 'converge' network (network with other traffic) to observe the behavior of each codec in different resolutions. A codec with high quality of video resolution is expected to perform in the simulations.…”
