Abstract: To solve the problem of physical layer security in industrial wireless sensor networks, a feedback Stackelberg game power control (FSPC) scheme is studied. Based on improving the security rate in one hop, encourage the destination node to provide cooperative jamming service by paying, where the Stackelberg game is used to simulate the interaction between the sending node and the destination node. Based on improving the security rate of multi-hop backbone network, the feedback cost function is introduced to reduce the fluctuation of the security rate between connected hops. The simulation results show, compared with other game power control algorithms without introducing feedback cost function, the proposed FSPC scheme can be more effectively to ensure the security of data transmission in the backbone network.
