This paper investigates the relay selection (RS) problem in full-duplex (FD) wireless networks with multiple users and multiple common relays. We consider three self-interference models at FD relays. For amplify-and-forward (AF) and decode-and-forward (DF) relaying, the exact and asymptotic expressions for the outage probability are derived over Rayleigh fading channels with distance-dependent path loss for three RS schemes i) optimal RS (ORS); ii) naive RS; and iii) random RS. Simulation results are provided to verify the analytical results.
