Peer-to-Peer Variable Service Transaction (P2P-VST) systems enable people to offer and receive help with a wide range of task types. However, such services are hampered by the difficulty of finding relevant and convenient opportunities for transactions ...

Recently, deploying the publish/subscribe model over Peer-to-Peer networks have been widely used for mobile applications. However, transfer delay and network load remain the challenging issues to consider for mobile subscribers because of their dynamic ...

Unstructured P2P networks have been widely used to implement resource location systems that support complex queries semantics. Unfortunately these systems usually rely on search algorithms based on some variant of flooding, which generate a significant ...

The proliferation of portable devices (PDAs, smartphones, digital multimedia players, and so forth) allows mobile users to carry around a pool of computing, storage and communication resources. Sharing these resources with other users ("Digital ...

Technology trends are not only transforming the hardware landscape of end-user devices but are also dramatically changing the types of software applications that are deployed on these devices. With the maturity of cloud computing during the past few ...

Peer-to-Peer P2P-based approach for on-demand video streaming systems P2P-VoD characterized by asynchronous user-interactivity has proven to be practical and effective in recent years with real-world Internet-scale deployment Huang, Li, & Ross, 2007. ...

Peer-to-peer systems are subject to frequent changes, fact which makes the resource management a very complex task. With the aim of reaching extreme scalability, centralized models no longer represent feasible solutions. Thus, we need to build flexible, ...

Large-scale complex infrastructures are emerging as new computing platforms for the federation of world-wide mission critical systems over the Internet. However, standard approaches to data dissemination are still not adequate to the scale of these ...

Recommendation-based reputation assessment in peer-to-peer systems relies on recommendations in predicting the reputation of peers. In this paper, we discuss the effectiveness and cost metrics in the recommendation retrieval. We evaluate the following ...

A distributed hash table (DHT) with replicated objects enjoys improved performance and fault-tolerance but calls for effective replica management. This paper deals with proximity-aware distributed mutual exclusion (PADME) for P2P replica management on a ...

This paper introduces the PeerSE Experiment Environment(EE) including concepts for a simulation-based analysis and implementation of P2P systems. The PeerSE EE supports a comparative analysis of P2P system models to identify models fulfilling given ...

We investigate how to ensure efficiency (in the economic sense of the word) in structured networks, with a focus on heterogeneity. A network is structured if the network designer has predefined some relationships between individuals (aka. nodes). ...

Designing topologically-aware overlays is a recurrent subject in peer-to-peer research. Although there exists a plethora of approaches, Internet coordinate systems such as GNP (which attempt to predict the pair-wise O(N^2) latencies between N nodes ...

Multi-party voice-over-IP (MVoIP) services allow a group of people to freely communicate with each other via Internet, which have many important applications such as on-line gaming and tele-conferencing. In this paper, we present a peer-to-peer MVoIP ...

Much research in the last few years has been devoted to development of efficient structured peer-to-peer (P2P) overlay networks, which offer distributed hash table (DHT) functionality. Most of these systems have been devised as flat, non-hierarchical ...

We present a P2P filesharing system that allows redundant storage of shared files in a way that no participating server ever stores data that could compromise its operator. Instead, only fragments that do not contain any information about the original ...

This paper presents an application of the Fluid Stochastic Petri Net (FSPN) formalism for the analysis of the transfer time distribution in peer-to-peer (P2P) file sharing applications.The transfer of the resource follows a successful search; the ...

We try to analyze a generic model for 2-tier distributed systems,exploring the possibility of optimal cluster sizes from aninformation management perspective, such that the overall costfor updating and searching information may be minimized byadopting a ...
