Abstract: This work aims at minimizing the total transport power subject to the outage probability requirement for the dual-hop decode-forward relay cellular networks.In particular,this paper first presented the closed-form optimal total power consumed by the user node and the cooperative relay node under the constraint of the outage probability.Then,a distributed auction algorithm based on Acknowledgement(DAA-ACK) and an improved distributed auction algorithm(IDAA) were proposed to assign every user to suitable relay node.Simulation results show that every user node can find its best cooperative relay through limited message passing with neighbor relay nodes.
