Peer-to-peer (P2P) networks use the fundamental assumption that the nodes in the network will cooperate and will not cheat. In the absence of any common goals shared by the nodes of a peer-to-peer network, external motivation to cooperate and be ...

In ongoing research, a collaborative peer network application is being proposed to address the scalability limitations of centralized search engines. Here we introduce a local adaptive routing algorithm used to dynamically change the topology of the ...

In this paper, we describe our work in progress on the reasoning module of ec(h)o, an augmented audio-reality interface for museum visitors utilizing spatialized soundscapes and a semantic web approach to information. We used ontologies to describe the ...

Grid computing-- the assemblage of heterogeneous distributed clusters of computers viewed as a single virtual machine-- promises to serve as the next major paradigm in distributed computing. Since Grids are assemblages of (usually) autonomous systems (...

We propose a decentralized privacy-preserving approach to spam filtering. Our solution exploits robust digests to identify messages that are a slight variation of one another and a peer-to-peer architecture between mail servers to collaboratively share ...

In this paper, we propose a framework called CC-Buddy, for maintaining dynamic data coherency in peer-to-peer environment. Working on the basis of peer heterogeneity in data coherency requirement, peers in CC-Buddy cooperate with each other to ...

This paper describes a query algebra for queries over XML p2p databases that provides explicit mechanisms for modeling data dissemination, replication constraints, and for capturing the transient nature of data and replicas.

Content delivery networks have evolved beyond traditional distributed caching. With services such as Akamai's EdgeComputing it is now possible to deploy and run enterprise business Web applications on a globally distributed computing platform, to ...
