文摘This paper focuses on the energy efficient relay selection problem in a cooperative multi-relay network,aims to find the most energy efficient relay node for the source node while ensuring its minimum data rate requirement.The interaction between the source node and the relay nodes is modeled as a Vickrey auction game,when the source node broadcasts a cooperation request,the relay nodes compete for the cooperation,and the one with the minimum bid will be chosen which denotes the cost of the source node during the cooperation process,but it only needs to provide the minimum bid provided by the other relay nodes,which can encourage all the relay nodes to give the true bid.Besides,the minimum rate requirement of the source node will be ensured and the relay node taking part in the cooperation will gain some reward and the reward can be maximized by reinforcement learning(RL).
