%X <p>A mobile relay selection scheme used in the cellular network was designed, it divides the users into one-hop users and two-hop ones according to the path loss. The one-hop users receive signal from the Base Station (BS) directly. However, the two-hop users could choose the idle one-hop users as Relay Nodes (RN) with the global optimal throughput prediction relaying (GOTPR). The proposed algorithm puts the impact of bandwidth and channel quality onto the rate of communication into account adequately, adjusts the bandwidth of two-hop users based on the equality of throughput of access link and backhaul link, and acquires the optimal matching matrix with the maximum throughput by the Hungarian algorithm. Simulations presents that the proposed method could improve the cell edge users throughput and spectral efficiency significantly.</p>
