An Adaptive Relay Selection Scheme for Cooperative Communication in 5G Networks
Aiming at the relay selection problem in collaborative communication networks,a Bayesian inference-based relay selection scheme is proposed.The scheme extends the principle of amplify-and-forward protocol,and accurately calculates the poste-rior probability of the relay node.Then the optimal relay node for information transmission is selected.The simulation results show that the proposed scheme significantly improves the network performance in the case of constant signal-to-noise ratio.
