摘要

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. We describe existing research approaches for query processing in P2P systems, we suggest improvements and enhancements, and propose a unifying framework that consists of a modified DHT architecture, data placement and search algorithms, and provides efficient support for processing a variety of query types, including queries with one or more attributes, queries with selection operators (involving equality and range queries), and queries with join operators. To our knowledge, this is the first work that puts forth a framework providing support for all these query types.
