Example Embodiment

[0052] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the examples. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0053] This embodiment assumes that the wireless collaborative spectrum sharing network is a labor market. Wherein, the PU is the entrusting party, and the SU is the agent, which can provide cooperative spectrum sharing services. As an active party, PU provides SU with a transaction contract consisting of a series of contract terms, including cooperation power and remuneration.

[0054] The specific process is as follows:

[0055] First, before cooperative spectrum sharing, PU broadcasts pilot signals to surrounding SUs. If the surrounding SU receives the signal, it returns the ...

Abstract

The invention belongs to the technical field of a wireless collaborative spectrum sharing system and specifically relates to a collaborative spectrum sharing dynamic incentive mechanism design method based on the contract theory. The method is characterized by mapping a wireless collaborative spectrum sharing network into a labor market, introducing a market-driven contract model to a collaborative spectrum sharing mechanism, and establishing a primary user (PU) module and a secondary user (SU) model; and with selfishness of nodes in the cooperative spectrum sharing network and asymmetry of network information being taken into consideration, for dynamic characteristics of factors of wireless node location and channel conditions and the like, designing a dynamic contract model for two-stage collaborative spectrum sharing, and with incentive compatibility and participation constraint conditions being combined, realizing screening of the SU private information to encourage active participation in collaboration, thereby realizing a purpose of efficient utilization of wireless spectrum resources.

Description

technical field [0001] The invention belongs to the technical field of wireless collaborative spectrum sharing systems, and in particular relates to a method for designing a dynamic incentive mechanism for collaborative spectrum sharing based on contract theory. Background technique [0002] With the explosive growth of wireless services and applications, the contradiction between the supply and demand of spectrum resources and the low utilization rate of resources, the above bottlenecks have become urgent problems to be solved. The cooperative spectrum sharing technology utilizes the mutual cooperation between the primary user (Primary User, PU) and the secondary user (Secondary User, SU), and can effectively improve the spectrum utilization rate of the system. The key to the cooperative spectrum sharing technology is how to establish an accurate cooperative spectrum sharing model, which usually requires as complete network information as possible. However, in the actual c...
