基于信任网络的网格资源发现机制

如何有效地发现网格的计算资源和存储资源是影响网格性能的重要因素,已有的资源查找方法难以适应网格规格.利用网格结点之间存在的信任关系构建资源信任网络,并给出了信任网络构建的原理和方法.将主动发现和被动发现相结合,应用小世界原理,获得了优化的时间复杂度,发送了网格资源发现性能.分析表明,该模型在网格环境中具有良好的效果,是一种可靠、安全的方法.

Mechanism of Resource Discovery Based on Trust Network

How to effectively locate resources is a very important factor affecting the performance of Grid environment.The authors propose a novel method which utilizes trust relations existed implicitly among network nodes to construct a secure and available resource trust network(SARTN),meanwhile provide the theory and method of SARTN.Combining passively discovery with actively discovery,applying Small World theory,optimized time complexity is achieved, and the performance of Grid resource discovery is promoted.Through analysis,the proposed solution is scalable,secure and efficient in Grid.
