Free-riding is a major problem in peer to networks. One of the ways resolve this by using reputation management system. Each node provides resources nodes with higher reputation, as he himself gains proportion receiver’s reputation. So, free-riding becomes non-optimal strategy there no resulting gain, and hence available over time. An efficient accurate trust estimation method system needed for...

P (P2P) file sharing networks are an important medium for the distribution of information goods. However, there is little empirical research into the optimal design of these networks under real-world conditions. Early speculation about the behavior of P2P networks has focused on the role that positive network externalities play in improving performance as the network grows. However, negative ne...

MorphMix is a peer-to-peer circuit-based mix network to provide practical anonymous low-latency Internet access for millions of users. The basic ideas of MorphMix have been published before; this paper focuses on solving open problems and giving an analysis of the resistance to attacks and the performance it offers assuming realistic scenarios with very many users. We demonstrate that MorphMix ...

With the development of the P2P traffic, it brings us various kinds of services, but it also take over a large amount of network resources. Because of this, it affects other services which make it become the hot topic of academic research. As research continues, more and more identification methods are proposed. This paper introduces several popular identification methods from now on. We find P...

Increasing knowledge of paedophile activity in P2P systems is a crucial societal concern, with important consequences on child protection, policy making, and internet regulation. Because of a lack of traces of P2P exchanges and rigorous analysis methodology, however, current knowledge of this activity remains very limited. We consider here a widely used P2P system, eDonkey, and focus on two key...

We propose a new form of marketing called, person-to-person(p2p) marketing. This is characterized by three elements-consumer collectives (both private social networks and public communities) conducting tasks usually performed by firms, diminished firm control on the marketing process and customer empowerment due to the end of isolation. We see the impact of consumer collectives in virtually all...

The last few years witnessed peer-2-peer (P2P) and VoIP telephony gaining a tremendous popularity: Skype is beyond doubt the most amazing example of this new phenomenon, as its 170 millions users testify. In this paper, we propose a detailed measurement of Skype sources: we adopt a twofold methodology, using active experiments and passive measurement to gain knowledge about the traffic Skype ge...

We describe a P2P system that offers a distributed, cooperative and adaptive environment for bookmark sharing. DAD offers an adaptive environment since it provides suggestions about the navigation based on (a) the bookmarks, (b) the feedback implicitly provided by users and (c) the structure of the Web. Our system is fully scalable because of its peer-to-peer architecture and provides, also, an...

How to effectively share knowledge within organizations has been given much more attention in practice as well as in research. However, most of current approaches are based on the centralized network structure, e.g. a central knowledge repository, which has been considered inappropriate and ineffective to facilitate the process of knowledge sharing. On the contrary, in this study, we propose th...
