Problems solved by technology

The existing cooperative communication contract design mainly studies the static contract model. However, in the actual cooperative communication network, due to factors such as wireless user mobility and wireless channel fading, the network information of RN is changing.

Embodiment Construction

[0050] 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.

[0051] 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.

[0052] The specific process is as follows:

[0053] First, before the cooperative communication, the SU sends a broadcast contract signal to the surrounding RNs. If the surrounding RN receives the signal, it returns the signa...

Abstract

The invention belongs to cooperative communication technology field of wireless data transmission, and particularly relates to a dynamic contract incentive method for cooperative communication under related asymmetric information. The method introduces a contract theory based on market drive into a cooperative communication mechanism under related asymmetric information and establishes originatingnode models and relay node models by mapping wireless cooperative communication networks to labor markets; based on the selfishness of the relay nodes and the asymmetric nature of network informationin the cooperative communication network mechanism under related asymmetric information and the characteristics of wireless node types and channel conditions, the relay node private information screening is realized and the relay nodes are encouraged to participate in the cooperation so as to reach the goal of wireless data transmission cooperative communication through designing dynamic contractmodels running through two phases of cooperative communication under situations of incentive compatibility and individual rationality constraint; finally, dynamic contract models for cooperative communication under related asymmetric information are established so as to maximize benefits of two sides of cooperative communication.

Description

technical field [0001] The invention belongs to the technical field of wireless data transmission cooperative communication, and in particular relates to a dynamic contract incentive method for cooperative communication under related asymmetric information. Background technique [0002] With the explosive growth of wireless services and applications, the contradiction between communication supply and demand and low transmission efficiency, the above bottlenecks have become urgent problems to be solved. The cooperative communication technology utilizes the mutual cooperation between the source node (Source User, SU) and the relay node (Relay Note, RN), which can effectively improve the transmission efficiency of the system. The key to collaborative communication is how to establish an accurate collaborative communication model, which usually requires as complete network information as possible. However, in the actual cooperative communication network, due to factors such as ...
