N2 - In this paper, we introduce a new network coding scheme with adaptive redundancy for scalable video streams in multi-hop wireless networks. Since scalable video coding produces a high quality bitstream with various levels of quality, we propose to offer better protection for important video layers when the link experiences a poor quality. Our scheme adapts the amount of redundancy depending on the quality of the output link and packet's importance. Our approach uses nested windows inspired by unequal protection schemes for scalable video coding. We carried out a simulation based evaluation of our scheme considering packet loss and overhead metrics in various network scenarios. The results show that our scheme reduces the overall packet loss and offers a better protection for the base layer packets.
