Abstract As screen resolution and video decoding capability have increased, high-definition (HD) video in resolutions as high as 1920 x 1080 is rapidly becoming the standard. Ad-hoc streaming of HD video over 802.11 wireless networks, e.g., streaming from a mobile device to a television, is convenient for users, but is hampered by bandwidth restrictions of 802.11g and 802.11n. In particular, performance suffers if the 802.11 channel is crowded with many transmitting nodes or contains a hidden terminal. In this paper, we present a method for dynamically selecting an 802.11 channel frequency for transmitting HD video between a transmitting and receiving node in an ad-hoc connection. We consider both the selection of the initial 802.11 channel and the need to change the channel if video quality begins to suffer, while keeping the overhead of channel changes to a minimum. To the best of our knowledge, our work is the first to address ad-hoc channel selection on 802.11 with respect to the demands of HD video. Simulations conducted using OEFMON (Open Evaluation Framework for Multimedia Over Networks) have yielded preliminary but promising results.
