addresses the problem of keyword-based search in structured P2P networks. We propose a new keyword-based searching algorithm which can be implemented on top of any structured P2P overlay. We demonstrate that the proposed algorithm achieves very good searching results as it requires the minimum number of messages to be sent in
Social applications associate a set of user defined keywords named tags when publishing social objects in order to locate them later. We propose T-DHT, a hybrid unstructured-structured DHT based approach, to cope with the high demanding requirements of social applications, in a fully scalable, distributed and balanced
This paper proposed a structured p2p model called balance-peer, introduce a method to partition the data rang without any global information on the load to. Our Balance-peer model is used to realize a partition-by-keyword indexing service based on DHT with each node in the system responsible for part of the keywords
Distributed hash tables (DHTs) are very efficient for querying based on key lookups, if only a small number of keys has to be registered by each individual peer. However, building huge term indexes, as required for IR-style keyword search, are impractical with plain DHTs. Due to the large sizes of document term
In this paper, we propose novel techniques to reduce bandwidth cost in a continuous keyword query processing system that is based on a distributed hash table. We argue that query indexing and document announcement are of significant importance towards this goal. Our detailed simulations show that our proposed
