Resource Search in Decentralized Peer-to-Peer System and Its Current Issues
Shi Xiao-qiu · Jisuanji gongcheng · 2007
For decentralized peer-to-peer system,both distributed hash table(DHT) and flooding are deployed in resource search.Hybrid search model combines the advantages of the two techniques and is expected to be efficient for popular and rare contents.However,it must solve how to precisely identify the rare item in decentralized,self-organized P2P network,and current hybrid algorithms are still suffered from the problem of either the efficiency decrease or QoS decay in dynamic environment.And a prelimitary soluiton to this problem is also proposed.
