Description
Summary:In this paper, we propose a fuzzy logic-based application layer controlling algorithm for wireless multimedia communication to adjust the bit-rate of transmitted video according to cross-layer feedback information. To further improve the fast adaptation to possible bit rate adjustment proposed by the cross-layer controller, a general enhancement to the rate control algorithm of the video encoder based on the motion activity of the video sequence is also introduced. The proposed cross-layer controlling algorithm for wireless communication has been integrated into the cross-layer simulation platform and the results achieved when using the algorithm with H.264/AVC show that it provides a good and fast adaptability into changing wireless channel conditions and an enhancement in video quality is achieved compared to non-adapted situation.
