Research on parallel query and merging mechanism in super-peers networks
Xidao Luan · Computer Engineering and Applications Journal · 2011
For a super-peers network facing a few challenges such as network bottleneck and retrieval result duplicated,a mechanism to parallel query and merge the results retrieved is proposed.Firstly,in order to decrease super-peer burden,a method of selecting query-peer in a super-peer is presented.The method and algorithm can let a super-peer connect more client-peers in the scope of load capacity.A method of detecting duplicated results is presented,and a strategy of selecting down-load peer for duplicated results based on download data quantity and response time.The strategy can efficient reduce retrieval overlap,network transfers quantity for downloading results and response time for acquiring results.The experimental results show that the proposed mechanism is efficient.
