Capitalizing on Free Riders in P2P Networks
نویسندگان
چکیده
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 a P2P network. Rather than excluding free riders, in this paper we incorporate and utilize them to provide global index service to the files shared by other peers. The simulation results indicate that our model can significantly boost the search efficiency of a plain Gnutella, and the model is quite resistant to system churn rate and the ratio of free riding.

Counteracting free riding in Peer-to-Peer networks
The existence of a high degree of free riding is a serious threat to Peer-to-Peer (P2P) networks. In this paper, we propose a distributed framework to reduce the adverse effects of free riding on P2P networks. Our solution primarily focuses on locating free riders and taking actions against them. We propose a framework in which each peer monitors its neighbors, decides if they are free riders, ...
متن کاملA Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory
The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...

متن کاملFree Riding in Peer-to-Peer Networks: Review and Analysis
Abstract— The popularity of P2P network paradigm due to the inadequacy of the traditional client-server model to handle increasing exchange of resources amongst millions of users worldwide comes with lots of challenges. One of these challenges is the problem of free riding. Free riding has been identified as a threat to the existence of P2P networks, as it degrades utilization and network perfo...
متن کامل'Q-Feed' - An Effective Solution for the Free-riding Problem in Unstructured P2P Networks
This paper presents a solution for reducing the ill effects of free-riders in decentralised unstructured P2P networks. An autonomous replication scheme is proposed to improve the availability and enhance system performance. Q-learning is widely employed in different situations to improve the accuracy in decision making by each peer. Based on the performance of neighbours of a peer, every neighb...
