QoS Based Peer-to-Peer Network Search Model
Wei Lu, Xianyu Meng · 2006
At the present, there are many obstacles on the way of development and application for P2P network, such as difficult expansion, low efficiency and heavy loads on Telecom backbone etc. In this article, based on the current P2P model, a new P2P search model is proposed. The new P2P model logically groups the network and then builds the in-group and between-group search mechanism to improve search efficiency and the ability of expansion. Meanwhile, query-agent-based mechanism which is introduced in the group search greatly reduces the low bandwidth link loads as well as search delay and enhances the expansion ability of the whole network system
