• Transmitting multimedia data requires high bandwidth and low delay of the network. Today's wireless networks satisfy these requirements in ideal situations, but in practice multiple devices including those of neighboring networks share the same physical layer channel and the desired speeds in the wireless network can not be achieved. Traffic in one network causes interference to other neighboring networks. In this paper, we evaluate end user's playback quality of video content transmitted over a wireless network. We take into account the influence of interference from a neighboring network and define a multi-layer control strategy to maintain the quality on the network. Through simulations, we have obtained acceptable improvements in video playback quality by controlling the transmission power, the number of retransmissions, and other parameters at various layers.
