Abstract

The invention discloses a device and a method for selecting a cooperative relay node. The method comprises the steps of receiving cooperative power and cooperative power pricing information broadcast by at least one relay node; acquiring revenue capable of being obtained when each relay node serves as a cooperative relay node according to the received cooperative power and cooperative power pricing information; taking the relay node with the maximum revenue value as the cooperative relay node. With implementation of the method, the cooperative relay node of each source-target node pair can be obtained rapidly; the cooperative relay node is determined according to the cooperative power and the cooperative power pricing information of the relay nodes, and the relay node capable of obtaining the maximum revenue is taken as the cooperative relay node, communication cost can be reduced, and secure communication efficiency can be increased.

Description

technical field [0001] The present disclosure relates to the technical field of physical layer secure relay communication, and in particular, to a method and device for selecting a cooperative relay node. Background technique [0002] Utilizing the characteristics of wireless media broadcasting, the wireless communication source node can select nodes within the coverage of the transmitter as relay nodes. The relay node assists the information transmission from the source node to the destination node based on different cooperation strategies. For example, decode-and-forward (DF), amplify-and-forward (AF), etc., such transmission methods can significantly reduce system energy consumption, improve spectrum efficiency, enhance transmission reliability, and expand network coverage. range etc. [0003] When the information transmitted in the network has confidentiality constraints, relay cooperation can also be used to enhance the security of information transmission, such as th...
