In the power Internet of Tings (IoT) scenarios,numerous devices and complex electromagnetic environment cause time-varying broadband strong interference to wireless data transmission of the sensor nodes.To address this issue,a low-power data return method is proposed.Through synchronous scheduling,distributed real-time narrowband interference monitoring,optimal channel data uploading etc.,the probability of data collision under strong interference environment is greatly reduced and the communication capacity is improved,and the overall low-power characteristics of the system are guaranteed at the same time.The simulation results indicate that the proposed method shows a performance improvement of over two times in throughput compared to traditional methods.Additionally,the power consumption has also decreased by over 50％.In the whole,the proposed method greatly improves the communication capacity and reduces the power consumption.
