N2 - An auction-based algorithm is proposed for subcarrier assignment for multiple users amplify and forward (AT) orthogonal frequency division multiple access (OFDMA) system aiming to maximize the fairness index. The proposed algorithm is based on one-shot auction, where each user submits bids for all subcarriers at once based on the Shapley value, a well-known cooperative-game theoretic concept. The user evaluates each subcarrier based on an estimate of the Shapley value using optimal power profiles at the source and relay nodes. The subcarriers are then allocated to the users based on the submitted bids using an iterative algorithm that aims to maximize the fairness index. The system throughput and fairness indices are used to evaluate the performance of the proposed algorithm. Numerical results are used to show the merits of the proposed algorithm.
