On the Available Receiver Side Information in Wireless Network Coding

In this paper, the authors analyze how different amount of Receiver Side Information (RSI) available at the receivers of a broadcast channel will affect the overall network throughput. Two transmission schemes, namely Random Linear Network Coding (RLNC) and Round Robin Scheduling (RRS), are considered. Taking into account the differing amount of RSI available at each receiver, closed-form expressions of network throughput and asymptotic throughput at high SNR are obtained for a broadcast channel. Their results show that the asymptotic throughput of RLNC is always no worse than RRS no matter how much RSI is available at each receiver.
