Frequency reuse distance of A 2-hop virtual cellular network

There have been strong demands for higher speed data transmissions in mobile communications. To reduce the peak transmit power while increasing the data transmission rates, authors proposed a wireless multi-hop virtual cellular network (VCN). The first step of transition to VCN from the existing cellular network (CN) is an introduction of a 2-hop VCN. Automatic repeat request (ARQ) is indispensable technique in packet transmission. Since the delay time increases in the multi hop communication, the throughput performance of 2-hop VCN may degrade compared to the conventional 1-hop CN. However, the frequency reuse distance of 2-hop VCN may be shortened compared to the conventional 1-hop CN, since the transmit power decreases in the multi hop communication. In this paper, the relationship between the frequency reuse distance and throughput of 2-hop VCN with selective repeat (SR) ARQ is evaluated and compared to the conventional 1-hop CN case.
