IWSN物理层防全双工攻击节点的多层Stackelberg博弈模型

Multi-level Stackelberg game model against full-duplex attacking node in IWSN physical layer

针对工业无线传感器网络通信链路上存在的节点安全问题,提出一种可抵御节点攻击的多层Stackelberg博弈模型。选择最佳协作干扰节点协同抵御全双工攻击节点,将合法节点与攻击节点之间的对抗关系以及合法节点间的内部协作关系建模成多层Stackelberg博弈模型,分析博弈模型的闭式均衡解;设计分阶最优响应迭代算法求解Stackelberg博弈均衡。仿真结果表明,所提的最佳协同干扰节点选择方案对攻击节点具有较好的干扰效果且节省能耗;与其他功率控制模型相比,所提模型可有效增加协作干扰节点的收益,提高协作的积极性。

Aiming at the security problems of the node in the communication link of industrial wireless sensor networks,a multi-layer Stackelberg game model is proposed to defend against the node attacking.The optimal cooperative jamming node is selected to resist the full-duplex attacking node.The confrontation relationship between legal nodes and attacking node and the internal negotiation relationship between legal nodes are modeled as a multi-layer Stackelberg game model,and the closed form equilibrium solution of the game model is analyzed;A hierarchical optimal response iterative algorithm is designed to solve Stackelberg game equilibrium.From the simulation experiments,the proposed scheme has better jamming effect on attacking nodes and saves energy consumption,compared with other power control models,the proposed multi-level Stackelberg game model can improve the income of cooperative jamming nodes to increase the enthusiasm of collaboration.
