Distributed Hash Tables (DHTs) provide a scalable solution for data sharing in large scale distributed systems, e.g. P2P systems. However, they only provide good support for exact-match queries, and it is hard to support complex queries such as top-k queries. In this paper, we propose a family of algorithms which deal with efficient processing of top-k queries in DHTs. We evaluated the performance of our solution through implementation over a 64-node cluster and simulation. Our performance evaluation shows very good performance, in terms of communication cost and response time.
