文章针对博弈论在无线通信物理层安全中的应用,首先简要介绍了无线通信中的物理层安全和斯塔克尔伯格博弈(Stackelberg game)相关概念,然后提出一种基于斯塔克尔伯格博弈的资源管理算法,有效改善了协同无线网络的物理层安全性能。该算法将人工干扰节点建模为卖方,将中继节点建模为买方,通过双方之间的交互来实现人工干扰节点功率的有效分配,最终达到提高系统安全速率的目的。
In this paper, aiming at the application of game theory in the physical layer security of wireless communication, the concepts of physical layer security and Stackelberg game in wireless communication are briefly introduced. Then a new concept based on Starker Grid game resource management algorithm, effectively improve the collaborative wireless network physical layer security. The algorithm models the artificial interference node as the seller, and models the relay node as the buyer. Through the interaction between the two parties, the power of the artificial interference node can be effectively distributed, and finally the system security rate can be improved.
