Resource search in unstructured peer-to-peer system based on multiple-tree overlay structure
YU Jian-qiao, Jianwei Liao · Wuhan University Journal of Natural Sciences · 2007
We propose a multiple-tree overlay structure for resource discovery in unstructured P2P systems. Peers that have similar interests or hold similar type of resources will be grouped into a tree-like cluster. We exploit the heterogeneity of peers in each cluster by connecting peers with more capacities closer to the root of the tree. The capacity of a peer can be defined in different ways (e.g. higher network bandwidth, larger disk space, more data items of a certain type etc.) according to different needs of users or applications.
