摘　　要： 基于协作干扰机制,研究了分布式无线网络中,节点采取怎样的交互与合作策略能提升其物理层安全传输性能.该问题被建模成一个联盟形成博弈,并引入享乐设置,在此基础上提出一种分布式享乐博弈算法,以获取稳定的联盟结构.仿真结果表明,相比于非合作及基于放大转发的博弈机制,所提出的合作博弈机制可以大幅提高网络用户的平均安全传输性能. The interaction and cooperation strategies among sources and friendly jammers to improve their secrecy capacity with physical layer security in a practical decentralized wireless network are investigated.The problem was formulated as a hedonic coalition formation game,and then a distributed hedonic coalition formation algorithm was proposed to achieve the stable coalition. Simulation results showed the proposed scheme could significantly improve the average payoffs per user comparing with the non-cooperative case and the amplify-and-forward case.
