Szukana fraza: [Abstract = "Peer\-to\-peer \(P2P\) networks offer a cost\-effective and easily deployable framework for sharing content. However, P2P file\-sharing applications face a fundamental problem of unfairness. Pricing is regarded as an effective way to provide incentives to peers to cooperate. In this paper we propose a pricing scheme to achieve reasonable resource allocation in P2P file\-sharing networks, and give an interpretation for the utility maximization problem and its sub\-problems from an economic point of view."]
