세미나 제목 : Multi-session Network Coding Characterization using New Linear Coding Framework

발표초록 :

Recently, Network Coding (NC) has emerged as a promising technique in modern communication networks. Nevertheless, the NC problem itself remains largely open especially where the multiple flows (sessions) exist. Unlike single-session where all receivers want the same information, they demand different set of information in multi-session and thus NC strategy should be carefully designed to avoid interferences. However, characterizing an optimal strategy (even a simple solution) has known to be of prohibitive complexity even we restrict to the linear network coding (LNC) problem. In this talk, we provide a fundamental approach to overcome this multi-session complexity, especially for Wireless Networks, where the linear NC designer needs to optimize the following three considerations all together: LNC encoding operations; scheduling between nodes; and the feedback and packet reception probabilities. In this model, we consider the multi-session capacity characterization problems: The first part will focus on the Shannon capacity region of the 3-node network with arbitrary traffic patterns. The second part will focus on the LNC capacity region of the 2-flow smart repeater network.
