Iterative Double-Auction-Based Power Allocation in Multiuser Cooperative Networks

In this paper, the authors study the power allocation problem in a multiuser cooperative network, where users help each other's transmissions to an access point. The authors use iterative double auction (IDA) game to model the interaction among the users and the access point. In each iteration of this game, the users first submit bids for buying other users' power and asks for selling its own power, and then, the access point determines the power allocation based on users' bids and asks. The authors propose a distributed algorithm for the implementation of the IDA-based power allocation. They also show that the proposed algorithm achieves a weighted sum signal-to-noise ratio (sum-SNR)-optimal solution. Simulation results are conducted to verify the performance of the proposed algorithm.
