ADAPTIVE SENSING DATA REPORTING METHOD FOR REDUCING NETWORK TRAFFIC IN SENSOR NETWORKS

摘要

Disclosed are a sensor node for reducing traffic in a sensor network and an adaptive sensing data reporting method. The sensor node according to an embodiment of the present invention compares the difference between a previously reported sensing value and a current sensing value with a threshold value, and reports the current sensing value when the difference is greater than the threshold value. The sensor node adaptively varies a period of a timer according to whether the current sensing value is transmitted based on a sensing value comparison result. When a current sensing value transmission occurs based on the sensing value comparison result, the sensor node additionally reports the current sensing value within the period of the timer.
