工业无线传感器网络物理层移动节点的抗干扰Stackelberg博弈模型

针对工业无线传感网络中物理层干扰攻击问题，研究一种移动环境下的博弈功率控制方案。为提高移动sink节点的抗干扰能力，利用Bayesion-Stackelberg博弈模拟移动sink节点和干扰节点的对抗交互行为，通过求出参与博弈的节点最优策略，即sink节点和干扰节点的最佳传输功率，达到合法节点抗干扰的最佳效果，提高通信系统物理层的安全性。Matlab仿真结果表明，相比移动sink节点的其他博弈功率控制算法，本文方案能更有效地提高合法节点抗干扰能力且能耗更低。 

Anti-Jamming Stackelberg Game Model of Mobile Node in Industrial Wireless Sensor Networks Physical Layer

? ?To solve the problem of physical layer jamming attack in industrial wireless sensor networks， a game power control scheme of mobile sink node is studied. To improve the anti-jamming ability of the mobile sink node， Bayesion Stackelberg game is used to simulate the antagonistic interaction between the mobile sink node and the jamming node. To achieve the better effect of legal node anti-jamming and improve the security of the physical layer of the communication system， the optimal strategy of the nodes involved in the game is worked out. That is the optimal sending power of the sink node and the optimal jamming power of the jamming node. The proposed scheme is compared with other game power control algorithms by using Matlab simulation， where the results show the proposed scheme can improve the anti-jamming ability of the legal node more effectively and consume less energy.
