Fast Sound File Characterisation Method
This article describes a fast technique of characterization of sound documents based on a statistical measure of the variation of the signal. We showed that a very limited sampling was sufficient to obtain a reasonable performance of the characteristic while being 100 times faster to calculate than a complete sampling. During preliminary tests, we carried out a first validation of our approach ...
متن کاملPopularity-Based Replication Strategy in Unstructured P2P File Sharing Systems
Peer-to-Peer (P2P) networks have shown to be an efficient and successful mechanism for file sharing over the internet. The unstructured P2P systems usually use a blind search method to find the requested data object. Observations have shown that a few of peers share most of data. In order to increase the success rate of blind search and data availability and load balancing, replication techniqu...
متن کاملAvailability and Popularity Measurements of Peer-to-Peer File Systems
Although peer-to-peer networking applications continue to increase in popularity, there have been few measurement studies of their performance. We present the first study of the popularity of files stored and transferred among peers in Napster and Gnutella over month-long periods. Our analysis indicates that the popularity of files is skewed in all four cases and fits well to a log-quadratic di...
متن کاملRelating Query Popularity and File Replication in the Gnutella Peer-to-Peer Network
In this paper, we characterize the user behavior in a peer-to-peer (P2P) file sharing network. Our characterization is based on the results of an extensive passive measurement study of the messages exchanged in the Gnutella P2P file sharing system. Using the data recorded during this measurement study, we analyze which queries a user issues and which files a user shares. The investigation of us...
متن کاملIntegrating File Popularity and Peer Generosity in Proximity Measure for Semantic-based Overlays
Peer-to-peer file sharing systems are now at the origin of most of Internet traffic. Improving the performance of such systems has generated a lot of interest both in industry and academia. More specifically, many approaches focus on the improvement of the query mechanism in such systems. In a peer-to-peer system, peers are connected to a subset of other peers with which they can communicate. E...
