摘要：In this article, firstly the principles of r esource discovery mechanism and the techniques involved in Multi-Layer Overlay Network (MLON) based grid resource discovery mechanism are introduced; then, using Euclidean space distance and Top-K technique, the resource matching strategy and the transformation of queries in multidimensional attribute space are discussed in detail, and a resource discovery algorithm MLON-RSA (MLON-based Resource discovery Algorithm) is proposed and theoretically analyzed; at last, the feasibility, high efficiency, and high user satisfaction of the proposed algorithm are demonstrated through simulation tests.
