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.
