Structured P2p Networks

چکیده
A number of Distributed Hash Table(DHT)based publish/subscribe(Pub/Sub) protocols have been proposed to address the issue of scalability in P2P networks. However, their routing state and control message overhead are enormous, the routing depth for notifications is unnecessarily long. We propose SGH, a large-scale partition-based overlay for P2P network, to provide the architecture of Pub/Sub routing. SGH relies on partitions where subscriptions and events are routed along distinct, albeit intersecting, sub-partitions. We design and implement the SGH event and subscription routing algorithms, and derive conclusions from the simulation experiments. The results show the simplicity of SGH model, and the scalability in Pub/Sub routing.

A Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory
The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...

In the past few years, resource discovery is an important mechanism in P2P applications. P2P networks could be categorized into structured and unstructured. In general, structured P2P networks (DHTs) provide efficient keyword search, but is difficult to offer a variety of search modes. Unstructured P2P networks are applied to highly churn P2P networks, but they are inefficient. In this paper, w...

The survey and classification of the different security attacks in structured peer-to-peer (P2P) overlay networks can be useful to computer system designers, programmers, administrators, and users. In this paper, we attempt to provide a taxonomy of structured P2P overlay networks security attacks. We have specially focused on the way these attacks can arise at each level of the network. Moreove...

Peer-to-peer applications (P2P) are no longer limited to home users, and start being accepted in academic and corporate environments. While file sharing and instant messaging applications are the most traditional examples, they are no longer the only ones benefiting from the potential advantages of P2P networks. For example, network file storage, data transmission, distributed computing, and co...
