Embodiment Construction

[0059] 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.

[0060] This embodiment assumes that the wireless collaborative communication network is a labor market. Wherein, SU is a client, and RN is an agent, which can provide collaborative communication services. As an active party, SU provides RN with a transaction contract consisting of a series of contract terms, including collaboration power and remuneration.

[0061] The specific process is as follows:

[0062] First, the SU broadcasts a set of contracts to nearby potential mobile nodes When receiving a contract, RN will inform SU of their choice if they are willing to accept a ce...

Abstract

The invention belongs to the technical field of wireless cooperative communication, and in particular relates to a dynamic contract incentive method for cooperative communication under independent asymmetric information. The method comprises the steps that: a wireless cooperative communication network is mapped to a labour market; a contract model based on market driving is applied in an independent asymmetric cooperative communication excitation mechanism; a source node model and a relay node model are established; in consideration of the selfishness of nodes and the asymmetry of network information in an independent asymmetric cooperative communication network, for dynamic and time-variant characteristics of the factors, such as wireless node positions and channel conditions, a dynamic contract model in two-stage cooperative communication is designed; in combination with individual reason and incentive compatibility conditions, discrimination on the private information of a relay node is realized, so that the relay node is stimulated to actively participate in data transmission; therefore, the purposes of effectively utilizing wireless spectrum resources and maximizing the interests of both parties are achieved; and finally, the model is optimized by establishing a dynamic contract incentive mechanism for cooperative communication under independent asymmetric information, sothat an optimal solution is obtained.

Description

technical field [0001] The invention belongs to the technical field of wireless cooperative communication, and in particular relates to a dynamic contract incentive method for cooperative communication under independent asymmetric information. Background technique [0002] The rapid development of wireless communication technology makes the problem of shortage of spectrum resources increasingly serious, which has seriously affected the development of wireless communication technology. The wireless cooperative communication technology utilizes mutual cooperation between a source node (Secondary User, SU) and a relay node (Relay Note, RN), which can effectively improve data transmission efficiency and indirectly improve the utilization rate of wireless spectrum. The key to the wireless cooperative communication technology is how to establish an accurate cooperative communication model, which usually needs to improve the network information of both parties as much as possible. ...
