Leaf degree keeping process of Gnutella is discussed in this paper. Queue system based on rules of Gnutella protocol are introduced to modeling this process. The leaf degree distributions resulted from the queue system and from our real measurement are compared. The well match of those distributions reveal that the leaf degree distribution in Gnutella network should not be power law or power la...

The use of peer-to-peer systems for sharing information, files and other resources has risen dramatically over the last three years. File sharing is the ‘killer app’ that has driven this explosion in popularity. The first generation of peer-to-peer file sharing systems, including Napster, Morpheus and Kazaa, followed the traditional client-server paradigm. However, concerns over the legality an...

To discover objects of interest in unstructured peer-to-peer networks, the peers rely on flooding query messages which create incredible network traffic. This article evaluates the performance of an unstructured Gnutella-like protocol over mobile ad-hoc networks and proposes modifications to improve its performance. This paper offers an enhanced mechanism for an unstructured Gnutella-like netwo...

Peer-to-peer network in general and specifically the Gnutella network suffer from poor search facilities due to their distributed and decentralized nature. Several improvements to the current implementations have been proposed, but the development of new improvements is hampered by the lack of a simple Gnutella simulator to test out algorithms on. The simulator that we developed is easy to use ...

As a developing P2P system, Gnutella has upgraded its protocol to 0.6, which significantly changed the characteristics of its hosts. However, few previous work has given a wide-scale study to the new version of Gnutella. In addition, various kinds of P2P models are used to evaluate P2P systems or mechanisms, but the reliability of some hypotheses used in the models are not carefully studied or ...

Peer-to-peer networking is a hot buzzword that has been sweeping through the computing industry over the past year or so. Gnutella, as one of the first operational pure P2P systems, is considered as an important case study for P2P networking. By analyzing the Gnutella network topology data, we can discover both the small diameter and the clustering properties characteristic of "small-world" net...

Despite recent excitement generated by the P2P paradigm and despite surprisingly fast deployment of some P2P applications, there are few quantitative evaluations of P2P systems behavior. Due to its open architecture and achieved scale, Gnutella is an interesting P2P architecture case study. Gnutella, like most other P2P applications, builds at the application level a virtual network with its ow...

The use of peer to peer file sharing networks such as Gnutella is proliferating on the Internet, but its use is bandwidth consuming due to the broadcast nature of some peer to peer protocols. This is undesirable for mobile devices due to their bandwidth and power constraints. This paper proposes an architecture that uses mobile agents to participate in the Gnutella network on behalf of mobile d...
