Middlemen in Peer-to-Peer Networks: Stability and Efficiency∗
نویسندگان
چکیده
A fundamental tension of between the efficiency and stability of social networks is now a well recognized fact in the literature. In general, networks are not simultaneously efficient and stable. Here we consider strongly pairwise stable networks and identify that the presence of middlemen is of particular importance for such a network to be efficient as well. We find that for the component wise egalitarian rule there is no conflict between the efficient and stable networks when these middlemen have no incentive to break up the network.

A 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...

Abstract— Peer-to-Peer ( P2P ) systems have been the center of attention in recent years due to their advantage . Since each node in such networks can act both as a service provider and as a client , they are subject to different attacks . Therefore it is vital to manage confidence for these vulnerable environments in order to eliminate unsafe peers . This paper investigates the use of genetic ...

متن کاملP2P Network Trust Management Survey
Peer-to-peer applications (P2P) are no longer limited to home users, and start being accepted in academic and corporate environments. While file sharing and instant messaging applications are the most traditional examples, they are no longer the only ones benefiting from the potential advantages of P2P networks. For example, network file storage, data transmission, distributed computing, and co...
متن کاملTAC: A Topology-Aware Chord-based Peer-to-Peer Network
Among structured Peer-to-Peer systems, Chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. However, Chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing late...
