세미나 제목 : A Joint Fountain Coding and Network Coding Approach  to Loss-Tolerant Information Spreading

발표초록 : 

In this talk, I will present a joint FoUntain coding and Network coding (FUN) approach to address the problem of information spreading over lossy communication channels. Different from the Transmission Control Protocol (TCP), our FUN approach is a mechanism of Forward Error Correction (FEC), which does not use retransmission for recovery of lost packets. The novelty of our FUN approach lies in combining the best features of fountain coding, intra-session network coding, and cross-next-hop network coding. As such, our FUN approach is capable of achieving unprecedented high throughput and low delay while allowing uncoordinated multiple source transmission of the same file to the same destination.  FUN is well suited for peer-to-peer Content Delivery Network (CDN), file transfer from distributed storage networks, social networks,  social TV, and mobile TV. Experimental results  demonstrate that our FUN approach achieves much higher throughput than existing schemes for multihop wireless networks.
