Sum-Rate Based Opportunistic Relay Selection Method For A Dual-Hop Multiple Half/Full-Duplex Bi-directional Wireless Relaying Networks

Abstract

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.
