Abstract
The prevalence of P2P technology contributes the ease of file-sharing to everyone, but it also brings some problem, for example, free-riding and copyright infringement. Many researches propose incentive mechanisms to solve these problems. At the same time, some applications based on P2P are developed. Although new business models have been proposed to apply P2P, those would not allow users re-distributing files they download. This study proposed a new business model which adopts a reselling mechanism to distribute contents on P2P networks; that is, users who download contents from a peer can resell them by paying a portion of reselling gain as royalty to the peer. The provider and consumers may re-price shared contents dynamically via incremental learning. Besides, this study aims to verify that authors can gain more through P2P reselling model than through client/server architecture, and we will investigate into the factors which influence the profitability.
