GcChord:enhanced DHT networks based on group and cache
Guizhu Wang · Computer Engineering and Applications Journal · 2007
Due to the mismatch between P2P overlay network and physical network,the routing latency is inefficient.This paper shows the idea that a topology-aware routing approach which uses groups and caches---GcChord(Group Cache based Chord).Experiment results demonstrate that GcChord improves the routing performance effectively,especially when nodes are apt to send some query more than others,both of the average logical hops and physical hop are improved observably.
