In this paper, we present a simulation study of network coding schemes
for multi-layer video streaming on multiple 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 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 simulations 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 packet loss.
