Aiming at the physical layer of industrial wireless sensor networks to resist the attack of mobile jamming nodes,the two-layer cooperative game model of the sink nodes and cluster-head nodes to resist the attack are studied.The best cooperative nodes are selected from cluster-head nodes to jointly resist the mobile jamming attack nodes.The cooperative competition among the sink nodes,the optimal cooperative nodes and the attack nodes are modeled as a two-layer cooperative Stackelberg game model.With the network security rate as the optimization objective,the backward induction method is used to solve the equilibrium solution of the game.The simulation results show that,compared with the scheme without cooperative nodes,the best cooperative nodes selection scheme adopted has a better resistance performance against mobile attack nodes,and compared with other game power control models,the two-layer cooperative Stackelberg game model can effectively improve the security rate of the industrial wireless sensor networks.
