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.
