摘要
A cross-layer collaboration method and a cross-layer collaboration system for a Cognitive Radio Network (CRN) are disclosed. The method includes: determining a transmission quality criterion (101); determining an ultimately working layer required for the transmission, and uniformly transmitting to the ultimately working layer the information of each layer required for determining transmission solutions (102); on the ultimately working layer, and according to the information of each layer, selecting the transmission solutions satisfying the transmission quality criterion (103); and evaluating the selected transmission solutions, determining an optimum solution according to the evaluation result, and transmitting data on the ultimately working layer by the optimum solution (104). The disclosure solves the drawback that the traditional cross-layer design solution only emphasizes single target optimization but neglects the overall network performance, thus avoiding the mutual conflict between multiple self-adaptive processes.
