Algorithm of resource discovery in dynamic grid
动态网格下的资源发现算法*

This paper put forward a representation for dynamic resources,which called matrix expression,and then gave the algorithms for discovering and updating resources.The two algorithms think of the dynamic characteristic of the resources.The efficiency improved greatly for the matrix instead of the original data.The method could be applied to equality queries but to range queries.When routed a local query,used local messages only to select the correct routes.This method also simplified the process of updating resources,which made the information of the resources close to the real state in time.
