Network Coding with Multimedia Transmission: A Software-Defined-Radio based Implementation

Recently, network coding (NC) has been considered as a breakthrough to improve throughput, robustness, and security of wireless network. Although there have been many theoretical studies on performance of NCs, there have been few experiments with pure NC schematics. This paper presents the first implementation of NC with multiple media transmission, which uses layered coding. The implementation is real-time and based on Software Define Radio (SDR) technique. The experimental results show that, by combining NC and source coding, we can control quality of received images on demand.
