Novel performance analysis of network coded communications in single-relay networks
In this paper, we analyze the performance of a single-relay network in which
the reliability is provided by means of Random Linear Network Coding (RLNC). We
consider a scenario when both source and relay nodes can encode packets. Unlike
the traditional approach to relay networks, we introduce a passive relay mode,
in which the relay node simply retransmits collected packets in case it cannot
decode them. In contrast with the previous studies, we derive a novel
theoretical framework for the performance characterization of the considered
relay network. We extend our analysis to a more general scenario, in which
coding coefficients are generated from non-binary fields. The theoretical
results are verified using simulation, for both binary and non-binary fields.
It is also shown that the passive relay mode significantly improves the
performance compared with the active-only case, offering an up to two-fold gain
in terms of the decoding probability. The proposed framework can be used as a
building block for the analysis of more complex network topologies.Comment: Proceedings of IEEE GLOBECOM 2016 Communication Theory Symposium, to
