Node Scheduling

IoT systems are heterogeneous network systems which consist of sensor terminals monitoring different objects. Terminal sensors have different sampling frequencies determined by minimum Nyquist sampling requirements. It is difficult to ensure synchronization when monitoring data of different sensors is transmitted to the data center. In consideration of sampling requirements of different terminals and in order to upload the sampling data timely and avoid data congestion, an applicable node scheduling scheme is necessary. In this paper node scheduling algorithms are proposed in hierarchical IoT systems with cluster topologies. The IoT systems include IoT alarming systems and IoT monitoring systems. In the simulation test, node scheduling methods are tested and the validity is demonstrated quantitatively.
