SENSOR NETWORK SYSTEM AND METHOD FOR PROCESSING SENSOR DATA

摘要

According to a sensor network system and a method for processing sensor data, a sync node collecting sensor data from sensor nodes obtains prediction value by performing the same prediction algorithm as the prediction algorithm performed in the sensor node; updates the prediction value to a sensing value when the sensing value is received from the sensor node; stores the sensing value in the sensor data by corresponding to the updated sensing value; judge whether the sensor node is the representative node or not when the sensing value is not received from the sensor node; stores the prediction value if the sensor node is the representative node; fixes the prediction value based on the sensing value of the representative node in the cluster which the sensor node belongs to, if the sensor node is not the representative node; and stores the fixed prediction value in the sensor data by corresponding to the fixed prediction value.
