  • Robust multimedia transmission over heterogeneous wireless networks is challenging. A protocol architecture that considers cross layer interaction is required. In this paper, an adaptive cross layer unequal protection strategy is proposed for video transmission over wireless channels. This strategy performs joint optimization across application layer, link layer and physical layer to provide unequal protection ability for video bitstream with different priority. Experimental results show the extraordinary improvement in PSNR of the proposed adaptive cross layer strategy over a variety of channel conditions.
