The access of the Io T terminal influences the capacity of the data gateway channel, leading to unstable operation. Therefore, a method to predict the data gateway state under the secure access of the Io T terminal was presented. The shortest path optimization method was used to deploy the gateway routing nodes, and then the Io T channel transmission model was built. Moreover, the channel capacity analysis model was built by the cross-layer optimization theory. The channel capacity analysis model was solved by Lagrange dual decomposition method. Based on the singlecycle prediction model and the aggregation prediction model, the multi-cycle prediction model was constructed to predict the status of secure access data gateway in the Io T terminal. Simulation results show that the proposed method is more efficient and accurate.
