Abstract :
Aimed at the low search efficiency of manufacture resource on the traditional unstructured super-peer overlay network, a new optimization method of overlay network is presented for improving its performance in this paper. Firstly, a hierarchy tree of manufacture resource is build, and then the resource is identified according to the tree. The peer´s identification is calculated from all manufacturing resource identification stored in the peer. Then, the resource and the overlay are related according to their identification. Finally, all peers are clustered to form an interest community using the peer interest distance. The search request is restricted in the interest community. Experiment result shows that the scheme improves about 20 percent efficiency of resource query in compared with the before.
