基于自组织的网格资源发现方法的研究

为了提高网格资源发现的效率以及系统的稳定性,提出了一种可以自组织的三层网格服务资源结构.这种结构能够将系统中的结点进行有效的自组织,即结点按照各自的特点,自动组成虚拟组织并选出一个主索引结点,然后主索引结点动态地选出全局索引结点,另外还能够根据系统的具体状况选择适当的资源查找算法,从而提高了查找效率.仿真结果证明,这种结构是稳定可靠的,同时具有很高的查询效率.

Method of resource discovery in grid based on self-organized

In order to improve the performance of resource discovery and the stability of system,a three layers grid architecture is pre-sented in which the grid nodes could organize by themselves according to the characters that calculate by a special algorithm and elect a main index nodes which will elect the global index node dynamically,at the same time it chooses the appropriate algorithm of resource discovery.The result of simulation proves that it is efficient and steady.
