An Auction Approach to Distributed Power Allocation for Multiuser Cooperative Networks
This paper studies a wireless network where multiple users cooperate with each other to improve the overall network performance. The authors' goal is to design an optimal distributed power allocation algorithm that enables user cooperation, in particular, to guide each user on the decision of transmission mode selection and relay selection. Their algorithm has the nice interpretation of an auction mechanism with multiple auctioneers and multiple bidders. Specifically, in their proposed framework, each user acts as both an auctioneer (seller) and a bidder (buyer). Each auctioneer determines its trading price and allocates power to bidders, and each bidder chooses the demand from each auctioneer.
