Abstract: The present invention relates to a queue management method based on duty cycle control for an end-to-end delay guarantee in a wireless sensor network in order to guarantee time variable delay requirement by controlling both an adaptive duty cycle and a queue threshold in a variable network state. The method of the present invention comprises the steps of: confirming a control section if a delay-notification bit is transferred from a source node to a sink node; calculating a delay-notification bit reception ratio if control interval has elapsed as a result of the confirmation; determining a queue threshold value based on the calculated delay-notification bit reception ratio; calculating non-operating time of the control device by using the determined queue threshold value; and controlling the queue threshold value and the adaptive duty cycle by setting the control section.
