Aiming at the conflict between detection performance and energy consumption of spectrum detection in cognitive Internet of Things, it is modeled as a multi-objective optimization problem, and the trade-off solutions between performance and energy consumption are to be found. Furthermore, an artificial physics optimization algorithm is proposed to solve it. The calculation method of individual mass and particle force are designed. The simulation results show that the proposed algorithm can effectively reduce the energy consumption while keeping high detection accuracy, and it is suitable for the spectrum detection in the cognitive Internet of Things.
