The actual performance of video delivery over wireless networks is best\ncaptured through experimental studies over real testbed, which is crucial to\nuncover the technical problems and practical challenges of realizing the\nproposed video delivery techniques. Network coding (NC) provides a paradigm\nshift to optimize the network resources for enhancing the video quality as a\nresult of delivery over multi-hop wireless networks. In this paper, we propose\na novel framework for evaluating the performance of NC-based video delivery\nover multi-hop wireless networks. Based on an experimental testbed\nimplementation of inter-layer video coding and delivery, we propose a new\ngeneralized technique for multi-hop interlayer NC in enhancing video delivery\nquality. We evaluate the trade-off between complexity of multi-hop NC, and\nvideo quality gain. We provide clear recommendations for best design choices of\nNC-based inter-layer video coding and delivery over multi-hop wireless mesh\nnetwork considering link conditions and Packet Delivery Ratio (PDR). The\nresults show that using NC improves the layered video performance in single and\nmulti-hop network. The average number of decoded layers when using NC in single\nhop outperforms that when using NC in multi-hop.\n
