With the growth of computing power and the proliferation of broadband access to the Internet, the use of media streaming has become widely diffused. In this paper, we propose a Peer-to-Peer (P2P) media streaming system which can provide a large number of users with continuous media streaming services while dynamically adapting to changes in media popularity, peer leaves, and changes in network ...

Similarity searching is particularly important in fully distributed networks such as P2P systems in which various routing schemes are used to submit queries to a group of relevant nodes. This paper focuses on the maintenance cost models and performances of similarity search in the HON P2P system, where data and peers are organized in a high dimensional feature space. We show through extensive s...

Current peer-to-peer (p2p) full-text keyword search techniques fall into the following categories: document-based partitioning, keyword-based partitioning, hybrid indexing, and semantic search. This paper provides a performance evaluation and comparison of these p2p full-text keyword search techniques on a dataset with 3.7 million web pages and 6.8 million search queries. Our evaluation results...

We describe the XenoSearch system for performing expressive resource discovery searches in a distributed environment. We represent server meta-data, such as their locations and facilities, as points in a multi-dimensional space and then express queries as predicates over these points. Each XenoSearch node holds a portion of this space and the key goal of XenoSearch is to direct queries to those...

Distributed Hash Tables (DHTs) provide a scalable solution for data sharing in large scale distributed systems, e.g. P2P systems. However, they only provide good support for exact-match queries, and it is hard to support complex queries such as top-k queries. In this paper, we propose a family of algorithms which deal with efficient processing of top-k queries in DHTs. We evaluated the performa...

The distributed system is used that it's features of the fault tolerance and good performances. One of the distributed systems, a peer-to-peer tech. has high availability to share resources. However when peers wanna share resources, it isn't online like the peer using resources of the search time. Therefore we usually use the re-transmission method to download all resources. It's not good at th...

A fundamental problem with many peer-to-peer systems is the tendency for users to “free ride”—to consume resources without contributing to the system. The popular file distribution tool BitTorrent was explicitly designed to address this problem, using a tit-for-tat reciprocity strategy to provide positive incentives for nodes to contribute resources to the swarm. We show that although BitTorren...

In this paper, we proposed a SORBA (Shared Object Request Broker Architecture) model, an objectbased P2P model, which complies with an open architecture, and manages resources afforded through a new object called SOC(Shared Object Class) in order to solve problems attendant upon a P2P(Peer-to-Peer) model. Also, it is so designed as to enable it to be extensible in a variety of ways under a P2P ...

Recent years mesh-based Peer-to-Peer live streaming has become a promising way for service providers to offer high-quality live video streaming service to Internet users. In this paper, we make a detailed study on modeling and performance analysis of the pull-based P2P streaming systems. We establish the analytical framework for the pull-based streaming schemes in P2P network, give accurate mod...

Description: This book focuses on tools, modeling principles and state-of-the art models for discrete-event based network simulations, the standard method applied today in academia and industry for performance evaluation of new network designs and architectures. The focus of the tools part is on two distinct simulations engines: OmNet++ and ns--3, while it also deals with issues like paralleliz...
