摘　　要：为了解决传统资源发现机制不能很好地适应网格资源环境的问题,在有效组建网格资源虚拟组织的基础上,提出了资源虚拟组织中联系结点的选取原则和选取算法,通过该算法从具有相同资源类型的联系结点中选出管理结点。联系结点和管理结点之间采用类似二部图的方式进行连接,构成基于动态自组织覆盖架构的网格资源发现模型。从资源发现能力、资源发现效率和系统可扩展性等方面对该模型进行了综合评价,结果显示该模型适合网格资源的特征,在大规模网格系统中能够有效提高资源发现性能,仿真实验验证了该模型的有效性。In order to improve resource discovery efficiency in current large-scale, dynamic and heterogeneous grid resource environment, on the basis of the organizing grid resources virtual organizations effectively, the select principle and algorithm of contact nodes in the resources virtual organizations is proposed, the management nodes ware selected from contact nodes which with the same type of resources using this algorithm.A grid resource discovery model is discussed based on dynamic self-organized overlay framework（DSOF）.The upper layer of this model is a overlay framework which reflects the interconnection among contact nodes and management nodes.The comprehensive evaluation is discussed from resource discovery capability and efficiency, system scalability and other aspects of this model, the results revealed that this model adapts to the characteristics of grid resources and performs efficient in large-scale grid environment.The simulation and experiment verified the usefulness of this model.
