METHOD, SYSTEM, AND SENSOR FOR ADJUSTING DETECTION FREQUENCY OF SENSOR NODE

摘要

Provided in embodiments of the present invention are a method, system, and sensor for adjusting a detection frequency of a sensor node. When a to-be-detected target is detected to have left a detection area of the sensor node, a prediction is made on whether or not the to-be-detected target will enter a detection area of the neighboring node, thus acquiring a prediction result. A frequency instruction message for instructing the neighboring node whether to employ a high detection frequency or a low detection frequency for detection is transmitted to the neighboring node on the basis of the prediction result. Correspondingly, when the frequency instruction message received by the sensor node is a first frequency instruction message that instructs the sensor node to employ the high detection frequency for detection, the high detection frequency is employed for detection of the to-be-detected target. When the frequency instruction message received is a second frequency instruction message that instructs the sensor node to employ the low detection frequency for detection, the low detection frequency is employed for detection of the to-be-detected target. This reduces the overall power consumption of a wireless sensor network. The present invention relates to the technical field of sensors.
