On the Performance of Cooperative Multihop Communications

Cooperative communications is a promising technology to improve the performance of wireless networks. In this paper, the authors investigate the performance of a multihop communication system with regenerative relays in terms of Bit Error Rate (BER). They propose low complexity techniques, including a max-min cooperative approach I and II, for the relay and path selection. Simulation results indicate that when a channel in a direct link is good or high Signal to Noise Ratio (SNR), the proposed technique achieves a lowest BER.
