Initial designs of P2P systems such as Napster, Gnutella and Freenet have significant scaling problems. Recently several research groups have independently proposed a new generation of topology-aware P2P systems to support scalable routing and location schemes. As the P2P architecture is becoming popular and more systems are introduced, we feel it necessary to propose an abstract and generic to...

This work presents a gossip-based protocol, termed QuickPeer, which builds and maintains latency-aware overlay topologies. Such topologies are useful for several distributed applications, like distributed online gaming, context-aware P2P applications and QoS-aware publish/subscribe systems. The distinctive feature of QuickPeer is that it can manage large scale overlay topologies providing each ...

P2P technology provides an excellent vehicle for the distribution of digital content at low cost to the content producer and distributor obviating the need for publishing middlemen. However, P2P content sharing networks are flawed with freeriding and copyright infringement. Providing financial incentives is one solution to overcome these problems; however the introduction of payments as a metho...

As soon as anonymous peer-to-peer (P2P) storage networks came to be in the early 2000s [8, 9, 11, 14], developers found themselves with a new playground for creating privacy enhancing tools. In many ways different to the now dominant client-server architecture, a whole generation of distributed overlay services emerged, offering a viable option for asynchronous messaging and bulletin boards. To...

The prevalent mechanism to avoid congestion in IP networks is the control of the sending rate with TCP. Dynamic routing strategies at the IP layer are not deployed because of problems like route oscillations and out-of-order packet deliveries. With the adoption of P2P technology, routing is done also in these overlay networks. With multi-source download protocols peers upload and download to/fr...

A P2P system based on super-peer overlay shows good features of combining both advantages of hybrid and pure P2P systems. Most P2P applications being developed are based on the overlay networks composed of super-peers. Super-peer is a special peer acting as a server to a cluster of client peers. Selecting super-peers and constructing a super-peer overlay for clustering client peers are importan...

Modeling peer-to-peer (P2P) networks is a challenge for P2P researchers. In this paper, we provide a detailed analysis of large-scale hybrid P2P overlay network topology, using Gnutella as a case study. First, we re-examine the power-law distributions of the Gnutella network discovered by previous researchers. Our results show that the current Gnutella network deviates from the earlier power-la...

The availability of reliable network coordinate systems gives us the potential to build ad-hoc p2p local resource discovery systems. Motivated by the shortcomings of existing p2p topologies in fulfilling this cause, we propose a Meta-Overlay Graph that enables us to use any existing p2p system to perform local resource discovery. This paper also proposes a way of confining query messages to sma...

With the development of Internet of Things (IOT), Radio Frequency Identification (RFID) is a hot topic in recent years. However, the traditional RFID reader system has some drawbacks, such as the effective reading distance of the reader is very small, and the reading speed of the reader is very slow. In this paper, we propose a novel RFID reader system framework, which is based on Peer-to-Peer ...

In an on-demand streaming service on a P2P network, a client peer can receive parts of a video object from different peers instead of from just one server. For this, the client peer must find enough peers that have the required object. In this paper, we propose a method of constructing an overlay to search for objects efficiently for the ondemand streaming services on a pure P2P network. The pr...
