N2 - In this paper, we present a simulation study of network coding schemes for multi-layer video streaming on multi-hop wireless networks. We consider in this study mainly two points: the packet loss due to the wireless environment and the unequal importance of scalable video packets. First, we study generation based network coding schemes with static and adaptive redundancy to evaluate the effect of redundancy adaptation on packet loss rate. Second, we evaluate an extension of the Expanding Window concept with a hop-by-hop coding to highlight the effect of layer discrimination for scalable video streaming. Extensive simulations have been carried out using ns- 3 for two different video test sequences with quality scalability. The simulation results show that adaptive redundancy can decrease the packet loss rate and introduce less overhead while Expanding Window can improve the PSNR of the video by reducing the base layer's packet loss.
