A relay selection scheme based on link states for cooperative communication

The cooperative communication makes wireless transmission reliable utilizing special diversity, where the relay selection is one of important issues. In this paper, we propose a relay selection scheme exploiting SNR and success probability of the link between nodes in network, especially focus in the link between the source and the relay. Proposed scheme is compared with previous schemes by the simulation. The simulation results show that our scheme perform better than other schemes in terms of BER and throughput.
