Uma Arquitetura Híbrida para Buscas Complexas em Redes P2P

Péricles C. M. LopesRonaldo A. Ferreira

Despite numerous efforts in the past few years, efficient complex queriesin large-scale P2P networks remain an open and challenging problem. Massivedata and query replications are two popular techniques used to improve successrates and response times. However, proactive replication strategies may lead tolarge amounts of traffic and low efficiency if not handled with care. This paperpresents a hybrid architecture that relies on a lightweight network structure, ona predominantly unstructured network, to avoid unnecessary query replicationand to speed up query propagation in P2P networks. Simulation results showthat the proposed architecture outperforms the best known solution in number ofmessages, response time, number of hops, and success rate.
