We report the first experimental demonstration of conditional preparation of a nonclassical
state of light in the continuous variable regime. Starting from a nondegenerate optical …

Free riding in peer-to-peer (P2P) networks poses a serious threat to their proper operation.
Here, the authors present a variety of approaches developed to overcome this problem …

We consider the problem of fair resource sharing to optimize the performance of resource
sharing in peer to peer systems. Resource sharing systems currently face rational peers …

Query efficiency is a significant challenge in peer‐to‐peer (P2P) social networks. In this
paper, we build a trust‐aware semantic‐based query routing strategy to improve the …

Distributed hash tables (DHTs) promise to manage huge sets of key-value pairs in a peer-to-
peer manner. The content-addressable network (CAN) is a prominent variant of DHT. A …

Research on P2P data structures has tacitly assumed that peers readily participate in the
work, ie, are cooperative. But such participation is voluntary, and free riding is the dominant …

The aim of this article is to examine the relationship of large-scale Peer-to-Peer (P2P)
overlay networks and certain biological systems. In particular, we focus on organization …

Overlay networks are an important kind of P2P infrastructures. The range of applications and
requirements is broad. Consequently, our research objective are overlay networks which …

Distributed Hashtables (DHT) are intended to provide Internet-scale data management. By
following the peer-to-peer paradigm, DHT consist of independent peers and operate without …

The problem of supporting privacy preservation of XML databases within very large publish-
subscribe systems is rapidly gaining interest for both academic and industrial research. It …
