This paper evaluates outage probability (OP) of a path-selection protocol in multi-path multi-hop decode-and-forward (DF) relaying networks. In the considered protocol, relying on the end-to-end signal to interference-plus-noise ratio (SINR), the best path between the source and the destination is selected to enhance the outage performance under joint impact of co-channel interference and hardware imperfection. We derive exact and asymptotic closed-form expressions of the end-to-end OP for the considered protocol over Rayleigh fading channels. The simulation results are then presented to validate the theoretical results.
