Abstract
Network coding (NC) and relay selection (RS) are two well-known techniques for achieving higher throughput and spectral efficiency in wireless networks. In this paper, we study a multiple-source, multiple-relay network-coded cooperative (NCC) system. We propose a new smart decode-and-forward (DF) relay selection scheme which considers the source-destination links' outage status for relay selection. Assuming that the number of selected relays is less than the number of the sources, the selected relays will need to use linear network coding to combine their received information. To do this, the network coding coefficients have drawn from a generator matrix of a systematic maximum distance separable (MDS) code. Our analytical and simulation results indicate that the proposed scheme outperforms the conventional max-min relay selection schemes in terms of the outage probability (OP) and throughput.
