Towards a Unifying Framework for Complex Query Processing over Structured Peer-to-Peer Data Networks [chapter]

Peter Triantafillou, Theoni Pitoura
2004 Lecture Notes in Computer Science  
In this work we study how to process complex queries in DHT-based Peer-to-Peer (P2P) data networks. Queries are made over tuples and relations and are expressed in a query language, such as SQL.  ...  To do so, they rely, in general, on lookups of a distributed hash table, which creates a structure in the system emerging by the way that peers define their neighbors.  ...  Concluding Remarks With this work we make a first step towards developing a unifying framework for complex query processing in peer-to-peer data networks.  ...

Building self-organized image retrieval network

Stanislav Barton, Vlastislav Dohnal, Jan Sedmidubsky, Pavel Zezula
2008 Proceeding of the 2008 ACM workshop on Large-Scale distributed systems for information retrieval - LSDS-IR '08  
The proposed network model is strictly data-owner oriented so no data redistribution among peers is needed in order to efficiently process queries.  ...  Thus a shared database where each peer is fully in charge of its data, is created.  ...  As the underlying network authors used M-Chord [17] that is a structured P2P network in which the data are redistributed to achieve better data clustering.  ...
