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:

The secrecy rate of the source-destination link can be effectively improved with help of friendly jammers, but the jamming service is not free. Obviously, there exists a tradeoff between the friendly jammer and the source-destination pair. An optimal power allocation algorithm based on Stackelberg game was proposed. Based on the proposed two-level Stackelberg game model, the existence of unique globally optimal energy efficiency was proved, and the closed-form result of the optimal energy efficiency was derived. Simulations show that the proposed collaboration strategy is better than the average power allocation strategy in terms of energy efficiency. And multi-nodes collaboration could achieve better performance.

Key words: physical layer security, cooperative jamming, Stackelberg game
