N2 - In this paper, considering the secure transmission of wireless communication networks with multiple untrusted relays, a relay selection method based on Stackelberg game is proposed. In this method, the source node and the untrusted relays are modeled as the buyer and the sellers, respectively. In particular, the source node can encourage the untrusted relays to forward signals by paying power price. The proposed method not only helps the source node purchase the optimal forwarding power from untrusted relays to improve the system security rate, but also helps the untrusted relays maximize their benefits through the optimal price. Further, this paper proves the existence of Nash equilibrium, and proposes a distributed iterative algorithm to obtain the equilibrium solution. The simulation results show that the proposed relay selection method can improve the system security rate effectively.
