In order to overcome the problem of free-riding in current P2P system, we suggest applying social network theory. Based on our exploration of the overlapping research fields of social networks and peer-to-peer networks, we propose a new P2P framework within this paper. It specifies social network information that can be used in a P2P system to avoid performance inefficiencies caused by free-rid...

Popular P2P system with centralized coordinator (tracker), whose address can be found in the torrent metafile. Nodes divided into seeders owning a complete download of the file and leechers, which are still in progress of downloading the file. Upload decisions are made using a choking algorithm based on the download rates received from remote peers. At regular intervals an optimistic unchoke ta...

This paper examines the negotiation of an international environmental agreement in which di¤erent countries determine the (nonenforceable) promises of investment in clean technologies to be included in the agreement. Furthermore, it analyzes countries’ optimal investments in clean technologies, considering that, in addition to the utility that countries perceive from an improved environmental q...

This paper assesses the distribution of free-riding behavior among different qualities of business students, investigates their perception of the ethics of such behavior, and examines the extent of the usefulness of take-home tests in view of the inherent opportunity they provide for students to free-ride. The results show: (1) Students recognize free-riding for what it is and view it as unethi...

Most of the research in the field of peer-to-peer file sharing systems has concentrated on performance issues such as efficient file lookup, replicating files to improve file download speeds etc. However there is a new challenge that questions the very existence and usefulness of such systems in the form of ”Free Riding”. This paper studies the seriousness of the negative impact that free ridin...

eer-to-Peer(P2P) networks are powerful distributed solutions which do not rely on external servers and gather required resources from their users. Therefor fairness is an important feature for designers of these networks. To have a fair network we always want to prevent free-riding. One of the most important file-sharing protocols in P2P is Bittorrent. What separates Bittorrent from other P2P p...

Free riding in a multichannel supply chain occurs when one retail channel engages in the customer service activities necessary to sell a product, while another channel benefits from those activities by making the final sale. Although free riding is, in general, considered to have a negative impact on supply chain performance, certain recent industry practices suggest an opposite view: a manufac...
