This work presents an overlay multicast tree construction algorithm to support stable multimedia service over the Internet. While constructing a multicast tree, it takes into account not only the link delay, but also the peer stability. Since peers actually show dynamic and unstable behavior over peer-to-peer network, it is essential to consider the peer stability. Furthermore, the weighting factor...
In original Chord model,the semantic property of the content in the model is not taken into account. Besides,a node's logical ID is independent of its physical location,bringing tremendous delay to network routing.Aiming at the system instability of structured P2P model which is caused by the heterogeneity of nodes in model,this paper proposes a Structure P2P network based on the Chord (TI-CHORD)...
PeerCast is a classical software of P2P streaming media. In this paper, an NS2-based PeerCast network simulation system was constructed for simulating the PeerCast protocol. Then we found two shortcomings of the PeerCast and proposed a multipath transmission algorithm based on depth balancing. The results of our simulation experiments demonstrate that the proposed algorithm substantially improved...
Multi-view video streaming over P2P network has emerged as a scalable solution for providing multi-view video service on Internet, as it utilizes users' bandwidth resource to reduce streaming server's bandwidth cost when delivering the dataintensive multi-view video. However, the view switching behavior in multi-view video introduces excessive dynamic to the system, which brings two performance issues...
To the question of topology mismatch in structured P2P network, this paper presents a routing advanced algorithm using super-nodes and self-organizing clustering. The algorithm adds self-organizing clustering based on physical location information in structured P2P system, and each node decides whether it can become clustering header according to its ability. In this algorithm, a series of powerful...
A real-time, interactive video distribution system on Internet for large-scale users faces three bottlenecks: real-time performance, interactive performance and bandwidth pressure. This paper, based on the approach to establish a Real-time Peer-to-Peer network (RTP2P) with the minimum video data delay as the primary goal, and establish a hybrid framework of P2P and centralized networks, argues that...
Two main problems prevent the deployment of peer-to-peer application in a wireless sensor network: the index table, which should be distributed stored rather than uses a central server as the director; the unique node identifier, which cannot use the global addresses. This paper presents a multi-level virtual ring (MVR) structure to solve these two problems. The index table in MVR is distributed stored...
In this paper, we propose two algorithms for broadcasting a large data set with limited loads of all nodes on a DHT-based P2P network using a de Bruijn graph. One of the broadcast algorithms is applied to de Bruijn graphs with the restricted number of nodes. We prove that this algorithm broadcasts a data set along a degree-constrained spanning tree without global knowledge of a P2P network and that...
The current peer-to-peer (P2P) live streaming networks can be generally classified into two categories: tree-based and data-driven. The tree-based approach suffers from three limitations: interruptive delivery due to failures of high level nodes, unfair uploading (out-going) bandwidth utilization in leaf nodes and bandwidth bottleneck in nodes near the root. The data driven approach has been widely...
Modern enterprises employ hundreds of workstations for daily business operations, which consume a lot of energy and thus have significant operating costs. To reduce such costs, dynamic energy management is often employed. However, dynamic energy management, especially that for disks, introduces delays when an accessed disk is in a low power state and needs to be brought into active state. In this...
P2P networks can achieve high scalability since they distribute service contents/resources to multiple nodes in the network. In a P2P network, it is necessary to search the resource location on the network when we use some contents/resources. Space filling curve is known as technique to map information of the multi-dimensional space such as the location information onto the one-dimensional space such...
We consider a content sharing network of non-cooperative peers. The strategy set of each peer comprises, (i) client strategies, namely feasible request load splits to servers, and (ii) server strategies, namely scheduling disciplines on requests. First, we consider the request load splitting game for given server strategies such as First-In-First-Out or given absolute priority policies. A peer splits...
Peer-to-peer (P2P) network is a decentralized and self organized architecture for the sharing of resources such as files. P2P network on wired network (Internet) has been extensively studied. The advancement in the wireless and mobile technology has lead to the deployment of the P2P filesharing on mobile ad hoc networks (MANETs). The direct deployment of wired P2P network would result in poor performance...
The critical issue of P2P models for supporting Internet telephony are: users localization and their ldquoasynchronousrdquo nature. In this paper, we propose a new P2P-SIP architecture for Internet telephony; aims to support the asynchronous model that generally characterized P2P systems. The purpose is to optimize the global end-to-end delay, which is one of the main performance metrics for telephony...
For the demand of people to networks performance increasing, LTE is be chose for the way to execute the problem about the broad band evolution due to the advantage about itself. We find that adoption the peer-to-peer networks model can augment the data transfer, reduce the transmission power, expand the capability of the networks and account for the problem of the load balance. In this paper, we discuss...
Peer-to-peer networks are an increasingly popular solution for the distribution of media content to a large number of users, with limited investments for network infrastructures. The distribution of a real time video stream imposes strict performance requirements such as small playback delays and few frame losses. In this paper, we focus on peer-to-peer video streaming systems with tree or forest...
Aiming at the problem of how to efficiently manage and use cache content in P2P VoD system, a distributed cache management model (DCMM) for P2P VoD is proposed. In the model, peers distributed cache management model for P2P VoD systems whose caching media segments integrate a full program are organized into a ring. Any segment of a specific program can be found quickly within a ring. With the concept...
Chord is known to be limited in routing efficiency since all nodes are on the overlay without considering the underlying network topology. In this paper, a Chord routing algorithm based on limited network layer multicast, called MChord, is proposed, which uses multicast technology to obtain physical neighbor information for routing. Simulation shows that it can shorten network search delay greatly,...
Recent research efforts have demonstrated the promising potential of building cost-effective media streaming systems on top of peer-to-peer (P2P) networks. The P2P systems have long setup and source to end delay. We proposes a hybrid architecture MTreeTV which combines the use of P2P networks with dedicated streaming servers, and was proposed to build on the advantages of both P2P and CDN paradigms...
Wireless ad hoc networks consist of nodes which can communicate with each other in a peer-to-peer fashion over single hop or multi hops without any fixed infrastructure such as access point or base station. In flat topology there is no topology management concept and all the nodes participate in routing. In this paper the task of topology management for ad hoc networks is implemented using routing...
