Information searches are the most common application within social networks. Normally, the social network is modeled as a network graph, consisting of nodes (In the rest of the paper, unless otherwise specified, we will use the terms “user” and “node” interchangeably.) representing users within the network and edges representing relationships between users. Choosing the appropriate nodes to form an...
The success of P2P file sharing systems inspired the development of P2P streaming systems for delivering online multimedia service in the last few years. The capacity of P2P streaming systems, i.e., how many peers can be concurrently serviced by the system, depends on system configurations including network bandwidth, overlay network formation, QoS constraints, membership management, peer selection,...
Without considering the controversial issue such as copyright, file sharing is the most popular application in a Peer-to-Peer (P2P) network. Piece-based file sharing is an intuitive way to speed up the sharing process in a P2P network, such as the BT P2P network, and Rarest Piece First (RPF) is the most common way to distribute file pieces. As heterogeneous networks have been fast developing, the...
Peer-to-Peer (P2P) networks have been developed for resource sharing for years. In a P2P network, resource locating is the first and foremost challenge, including issues about long searching time, a large amount of duplicated query message and a small success rate. Many efficient methods have been proposed to resolve these issues. However, most of these proposals may only benefit searching a popular...
