The existence of a high degree of free riding in Peer-to-Peer (P2P) networks is an important threat that should be addressed while designing P2P protocols. In this paper we propose a connection-based solution that will help to reduce the free riding effects on a P2P network and discourage free riding. Our solution includes a novel P2P connection type and an adaptive connection management protoc...

A theoretical framework for protocooperative behavior in pelotons (groups of cyclists) is proposed. A threshold between cooperative and free-riding behaviors in pelotons is modeled, together comprising protocooperative behavior (unlike protocooperation). Protocooperative behavior is a function of: 1. two or more cyclists coupled by drafting benefit; 2. current power output or speed; and 3. cycl...

Free riding is a common phenomenon in P2P networks. Although several mechanisms have been proposed to handle free riding— mostly to exclude free riders, few of them have actually been adopted in practical systems. This may be attributed to the fact that they are nontrivial, and that completely eliminating free riders could jeopardize the sheer power created by the huge volume of participants in...

This paper studies negative externalities’e¤ect on bidding strategy and auction outcome. We use a model of one special bidder and two regular bidders, where if the special bidder wins, both regular bidders incur a loss; otherwise, the two losing bidders receive zero payo¤s. Applying the model to an ascending clock auction, regular bidders are shown to bid less aggressively and drop out before r...

Peer-to-Peer (P2P) is a self-organizing resource sharing network with no centralized authority or infrastructure, which makes it unpredictable and vulnerable. In this paper, we propose architecture to make the peer-to-peer network more centralized, predictable, and safer to use by implementing trust and stopping free riding. Keywords— File Share, Free Riding, Peer-to-Peer, Trust.

9 We ask whether conformity, copying the most observed behavior in a population, affects free riding. 10 Our model suggests that, if sufficiently frequent at the start of a public goods game, conformity will 11 increase the growth rate of free riding. We confirm this prediction in an experiment by showing that 12 free riding grows faster when players have the information necessary to conform. A...

This paper experimentally investigates free-riding behavior on communication cost in a coordination game and finds strong indications of such free-riding. Firstly, the subjects wait for others to send a message when communication is costly, which does not happen when communication is costless. Secondly, the proportion of games where no communication or one-way communication takes place is much ...

BitTorrent is undoubtedly the most popular P2P file sharing systems in existence that has been able to attract millions of users. BitTorrent depends on global components for file search, engages a moderator system to guarantee the data integrity of file, and uses an exchange mechanism for file sharing in order to discourage users from free-riding. We conduct one of the largest measurement and a...
