Recall-Based Cluster Reformulation by Selfish Peers ABSTRACT (2008)
Georgia Koloniari, Evaggelia Pitoura
Recently, clustered overlays in which peers are grouped based on the similarity of their content or interests have been proposed to improve performance in peer-to-peer systems. Since such systems are...
ABSTRACT Query Workload-Aware Overlay Construction Using Histograms (2008)
Georgia Koloniari, Yannis Petrakis, Evaggelia Pitoura, Thodoris Tsotsos
Peer-to-peer (p2p) systems offer an efficient means of data sharing among a dynamically changing set of a large number of autonomous nodes. Each node in a p2p system is connected with a small number...
Bloom-Based Filters for Hierarchical Data 1 (2008)
Georgia Koloniari, Evaggelia Pitoura
Abstract. In this paper, we present two novel hash-based indexing structures, based on Bloom filters, called breadth and depth Bloom filters, which in contrast to traditional hash based indexes, are...
Peer-to-peer management of XML data: Issues and research challenges (2005)
Georgia Koloniari, Evaggelia Pitoura
Peer-to-peer (p2p) systems are attracting increasing attention as an efficient means of sharing data among large, diverse and dynamic sets of users. The widespread use of XML as a standard for...
04441 Working Group -- Description and Matching of Services in Mobile Environments (2005)
Grünbauer, Johannes, Klein, Michael, Koloniari, Georgia, Samaras, George, Türker, Can
Service oriented computing is a new paradigm that is especially interesting in mobile environments. As a characteristics, functionality is hidden behind an interface and described as a black box with...
Peer-to-peer systems are gaining increasing popularity as a scalable means to share data among a large number of autonomous nodes. Since the shared data are unstructured and they do not follow a...
Filters for XML-based service discovery in pervasive computing (2004)
Georgia Koloniari, Evaggelia Pitoura
Pervasive computing refers to an emerging trend towards numerous casually accessible devices connected to an increasingly ubiquitous network infrastructure. An important challenge in this context is...
On using histograms as routing indexes in peer-to-peer systems (2004)
Yannis Petrakis, Georgia Koloniari, Evaggelia Pitoura
Abstract. Peer-to-peer systems offer an efficient means for sharing data among autonomous nodes. A central issue is locating the nodes with data matching a user query. A decentralized solution to...
Content-based routing of path queries in peer-to-peer systems (2004)
Georgia Koloniari, Evaggelia Pitoura
Peer-to-peer systems are gaining popularity as a means to effectively share huge, massively distributed data collections. An important challenge in this context is discovering the appropriate data...

Bloom-Based Filters for Hierarchical Data (2003)
Georgia Koloniari, Evaggelia Pitoura
In this paper, we present two novel hash-based indexing structures, based on Bloom filters, called Breadth and Depth Bloom filters, which in contrast to traditional hash-based indexes, are able to...
Content-based overlay networks of XML peers based on multi-level bloom filters (2003)
Georgia Koloniari, Yannis Petrakis, Evaggelia Pitoura
Abstract. Peer-to-peer systems are gaining popularity as a means to effectively share huge, massively distributed data collections. In this paper, we consider XML peers, that is, peers that store XML...
