With the encouragement from success of P2P systems in real world application, recently we have seen active research on synergy of P2P systems and mobile ad hoc networks. The paper proposes a solution for mobility disturbance problem in initialization of ring-based P2P systems over ad hoc networks. It is a decentralized ring construction protocol in presence of mobility. A Mobile Ring Ad-hoc Net...

Complex network theory is a useful way to study many real systems. In this paper, an anti-attack model based on complex network theory is introduced. The mechanism of this model is based on dynamic compensation process and reverse percolation process in P2P networks. The main purpose of the paper is: (i) a dynamic compensation process can turn an attacked P2P network into a power-law (PL) netwo...

The popularity of mobile applications utilizing wireless networks is growing as increasingly capable terminals and advanced networking technologies emerge. At the same time, Peer-to-Peer (P2P) networking is becoming more and more important as a technology for a general-purpose communication system. Based on these developments, P2P networking has also became an interesting option for mobile inte...

Peer-to-peer (P2P) recently emerged as a new paradigm in computer science. Due to majoreconomic and social stakes, mostly related to content distribution, P2P has brought back to theforefront many existing research elds related to distributed systems, providing new incentivesand goals.In this work, we give some keys to the understanding of the research elds related to P2Psys...

Peer-to-peer (P2P) systems are widely used to exchange content over the Internet. Knowledge of pedophile activity in such networks remains limited, despite having important social consequences. Moreover, though there are different P2P systems in use, previous academic works on this topic focused on one system at a time and their results are not directly comparable. We design a methodology for c...

Though a few previous research efforts have investigated the peer availability of P2P systems, the understanding of peer dynamic is far from adequate. Based on the running log of a file-sharing P2P system, we produced a more thorough measurement of the dynamic natures of P2P system. We further show that due to the methodology limitation, crawler based measurement can not precisely capture syste...

In this work we consider a general-purpose application for ECommerce transactions over Peer-to-Peer (P2P) network. Weakly organized structure of P2P systems may cause data management problems and high communication overhead. We resolve these problems by developing a novel semantic approach to efficiently create, search and organize demand and supply advertisements in E-Commerce P2P applications...

With the extending of spatial information system into the distributed network environment, it faces some challenges including the mass data character of the spatial data, the limited band width of current network, the devilishly centralized spatial information management and geographic computing resources, as well as the higher requirements of the spatial information service capability. For ove...

This paper focuses on the sampling-based Deep Packet Inspection for the traffic of P2P file sharing systems, especially for BitTorrent, and proposes a logarithmic-based Adaptive Trust Sampling (ATS) strategy for P2P traffic identification. In the whole process of sampling identification for P2P traffic, the sampling ratio of the current node in a P2P network can automatically adjust and dynamic...
