Auction-Based Fair Partner Selection for Decode-and-Forward Cooperative Relay Networks

Abstract

In this paper, we propose a fair partner selection scheme for decode-and-forward cooperative relay networks based on auction theory. Modelling a single relay node as an auctioneer and multiple source nodes as bidders, the source nodes compete with each other by offering competitive prices to determine the recipient of the cooperative resources. To maximize the expected payoff, a closed-form Nash equilibrium strategy for each source node is derived over independent and identically distributed Rayleigh fading channels. Finally, numerical results and analysis verify the effectiveness of the proposed schemes.
