SENSOR NODE, HOST, AND SENSOR NETWORK SYSTEM

To suppress power consumption of a sensor node in a sensor network system.SOLUTION: The sensor node includes: a sensor; a sensor node transmission section for transmitting a measuring signal including a measured value measured by the sensor to a host; a sensor node reception section for receiving a response signal including a control information corresponding to a comparison result between the measurement value and a prediction value from the host; and a sensor node control section for setting transmission time of the measurement value signal on the basis of the control information.SELECTED DRAWING: Figure 2
