On the performance of cooperative multihop communications

Cooperative communications is a promising technology to improve the performance of wireless networks. In this paper, we investigate the performance of a multihop communication system with regenerative relays in terms of bit error rate (BER). We 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.
