Network coding with multi-generation mixing for scalable and non-scalable video communication
Network coding with multi-generation mixing (MGM) has been proposed as a generalized approach for practical network coding [6]. Our goal in this paper is to evaluate the improvements achieved by MGM network coding on the quality of recovered video in packet loss networks. The improvements of network coding are clear in wireless networks due to the opportunities of enhancing bandwidth utilization. This makes MGM network coding appropriate for video communication over wireless networks. In this paper MGM is applied on scalable as well as non-scalable video. MGM deployment in the case of scalable video differs from that in the case of non-scalable video. After explaining the way MGM is applied, we evaluate the performance with extensive simulations in a wireless network setup. Results indicate major improvements in network coding decodable rates and enhancement in the quality of recovered video with MGM.
