Sum-rate based opportunistic relay selection method for a dual-hop multiple half/full-duplex bi-directional wireless relaying networks

This paper investigates the opportunistic relay selection method for bi-directional wireless relaying networks. The investigation considers a dual-hop network with a multiple half/full-duplex two-way relay terminal in the system model. The sum-rate based opportunistic relay selection (SR-ORS) strategy selects the best relay terminal based on maximum sum-rate of user-pair and related relay terminal. According to analytical, asymptotic and Monte-Carlo simulation results, the SR-ORS strategy provides better performance results when the relay terminal operates in full-duplex mode.
