This paper proposes an adaptive error control mechanism for wireless video streaming, in order that the video data over wireless could be played on receiving sides with high quality. This model, based on GM (1, 1) model and cross-layer design, which adaptively select different error control techniques for every packet at the data link layer, to adjust to the current network condition and meet the different requirements of wireless link, is able to improve the performance of wireless video data transmission. The NS simulation and experiments of video data transmission over wireless network are carried out to validate, and characterize the performance of the proposed approach.
