This paper proposed a new method of topology construction based on grid coordinates autonomous domain. In order to build a topology matching overlay networks, this paper presented the node mapping mechanism to guarantee that the nodes adjacent to each other in physical network were also neighbors in overlay network. In addition, it proposed the resource searching strategy based on the hierarchical index according to the proposed architecture. The simulation results show that strategy can effectively improve the success rate of searching and reduce the average path length.
