【摘要】：協(xié)作干擾策略是實現(xiàn)物理層安全的一種重要方案.但是由于協(xié)作節(jié)點的能源有限性以及自私性,干擾服務不能無償提供,為了使得源節(jié)點和協(xié)作節(jié)點之間取得最優(yōu)的效益分配,提出了一種基于Stackelberg博弈的能效最優(yōu)報償及功率分配方案.根據所建立的雙層博弈模型,證明了系統(tǒng)存在唯一的全局最優(yōu)能效,并且給出了最優(yōu)功率分配方案的閉式解.仿真結果表明,所設計的協(xié)作策略在能效方面優(yōu)于平均功率分配策略,而且所提方案在多節(jié)點協(xié)作時能取得更優(yōu)的表現(xiàn).
[Abstract]:Cooperative interference strategy is an important scheme to realize physical layer security. However, due to the limited energy and selfishness of cooperative nodes, interference services can not be provided free of charge. In order to achieve the optimal benefit distribution between source nodes and cooperative nodes, an energy efficiency optimal reward and power allocation scheme based on Stackelberg game is proposed. According to the established two-layer game model, it is proved that the system has a unique global optimal energy efficiency, and the closed solution of the optimal power allocation scheme is given. The simulation results show that the designed cooperation strategy is superior to the average power allocation strategy in energy efficiency, and the proposed scheme can achieve better performance in multi-node cooperation.
