Embodiment Construction

[0023] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings. figure 1 It is a flow chart of a Bayesian game-based spectrum sensing secondary user incentive method for the technical solution of the present invention.

[0024] The basic idea of ​​the present invention is to apply the incentive mechanism in crowd sensing to collaborative spectrum sensing to solve the incentive problem for secondary users. Secondary users can choose strategies independently to obtain optimal benefits. The method is to apply the Bayesian game incentive mechanism to cooperative spectrum sensing, and the secondary users independently choose strategies to optimize the utility, and encourage secondary users to participate in spectrum sensing, thereby improving the detection probability.

[0025] The present invention is based on the Bayesian game-based spectrum sensing secondary user incentive method, comprising the following s...

Abstract

The invention discloses a cooperative frequency spectrum perception method based on motivation. The method is characterized by adding a Bayesian motivation mode to frequency spectrum perception research; providing a frequency spectrum perception secondary user motivation algorithm based on the Bayesian game; adopting the Bayesian game motivation mode to motivate a secondary user to participate infrequency spectrum perception so that the secondary user can choose an optimal strategy to participate in perception or not so as to achieve optimal benefits; and then, sending the perceived data to afusion center by the secondary user participating in the perception, fusing the data through a voting fusion mode, and determining whether a master user exists by the fusion center.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a method for stimulating secondary users of spectrum sensing based on Bayesian game. Background technique [0002] With the rapid development of wireless communications, the requirements for spectrum resources are also increasing, and wireless spectrum resources have become a very scarce resource. The emergence of cognitive radio in 1999 provided an effective method for spectrum access, enabling wireless communication devices to discover and rationally utilize spectrum resources, so as to solve the problem of lack of spectrum resources and improve spectrum utilization. It is very important to accurately detect the existence of primary users in a cognitive radio network (CRN, cognitive radio network), so spectrum sensing has become a core technology of cognitive radio. Spectrum sensing technology can be divided into single-user sensing and cooperative spectrum sensing accordi...
