We analyze the outage performance of a buffer- aided dual-hop decode-and-forward cooperative relaying network with co-channel interference (CCI) and additive white Gaussian noise (AWGN) at the relay and the destination nodes. We propose a max-signal-to-interference plus noise ratio (max- SINR) relaying protocol in which the data transmission takes place in the link having the maximum SINR among the available source-relay and relay-destination links. It is assumed that the envelopes of the desired signal and the interfering signal follow asymmetric channel configuration with Rayleigh distributed fading. We consider a finite size data buffer equipped at the relay nodes. A discrete Markov chain approach is adopted to model the evolution of the relay buffers' status and to derive a closed-form expression for the outage probability. Numerical results demonstrate that in the cooperative networks with CCI and AWGN, employing a data buffer at the relays and adopting the max- SINR relaying protocol lead to an improvement in the performance of outage in comparison to the max-min relaying protocol without a buffer. The buffer-aided relaying protocol can improve the reliability of a cooperative network with CCI and AWGN as compared to the non buffer-aided relaying protocol.
