Document Type and Number:
WIPO Patent Application WO/2023/231165
Kind Code:
A1
Abstract:
Disclosed in the present invention is a multi-band crowd-sourcing spectrum sensing method based on Stackelberg competition. The method comprises: modeling the problem that second users having a sensing demand pay rewards to cooperative sensing second users as a competition model, wherein the second users having the sensing demand are in a leadership level, and the cooperative sensing second users are in a subordinate level. Each second user having the sensing demand issues a band sensing task and an initial reward, the cooperative sensing second users optimize the utility thereof by optimizing a sensing time, and send sensing data to the second user having the sensing demand, and the second user having the sensing demand continuously updates the reward to optimize the utility and obtain a final determination result. According to the present invention, the utility of the second users having the sensing demand is defined by comprehensively considering the detection probability and the reward in the competition of the leadership level, and the optimal utility is obtained by optimizing the reward by means of competition; and the utility of the cooperative sensing second users is defined by comprehensively considering the detection probability and the sensing time in the competition of the subordinate level, the optimal utility is obtained according to the reward issued by the second users having the sensing demand, and the optimized sensing time, and it is derived and proved that a Nash equilibrium exists in the optimization of the sensing time.
