One of the purposes of network tomography is to infer the status of parameters (eg, delay) for
the links inside a network through end-to-end probing between (external) boundary nodes …

We propose an efficient technique for improving the performance of automatic and
cooperative compositions in unstructured Peer-to-Peer networks during service discovery …

Reputation systems are essential to establish trust and to provide incentives for cooperation
among users in decentralized networks. In these systems, the most widely used algorithms …

Since the emergence of peer to peer networks, search efficiency in such networks has been
a matter of great concern, as it directly effects resource management of the network and …

Existing unstructured peer-to-peer networks have low efficiency to locate the rare objects.
Although various algorithms have been provided to address this problem, they do not …

In this paper, a new search algorithm in heterogeneous hierarchical unstructured p2p
networks is presented which takes into account heterogeneity of peers such as upload …

Success rate, query hit rate and speed of search are some common metrics for evaluating
p2p search algorithms. Yet, these metrics do not consider properties of discovered sources …

Unlike those on Internet, the media providers on P2P networks are ordinary nodes with
limited shared resources such as bandwidth. Multi-sender methods are the best existing …

An efficient structured peer-to-peer (P2P) network should guarantee the search always
convergent. This paper presents analytical models to characterize the process of locating …

P2P (Peer-to-Peer) technologies are well established and have now become accepted as a
mainstream networking approach. However, the explosion of participating users has not …
