【摘要】：协作干扰策略是实现物理层安全的一种重要方案.但是由于协作节点的能源有限性以及自私性,干扰服务不能无偿提供,为了使得源节点和协作节点之间取得最优的效益分配,提出了一种基于Stackelberg博弈的能效最优报偿及功率分配方案.根据所建立的双层博弈模型,证明了系统存在唯一的全局最优能效,并且给出了最优功率分配方案的闭式解.仿真结果表明,所设计的协作策略在能效方面优于平均功率分配策略,而且所提方案在多节点协作时能取得更优的表现.
[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.
