Improving Reliability through Selecting Data in Grid Distributed System and Comparing it with Other Presented Algorithms

In the past, one of the biggest problems requiring long and complicatedcomputing was lack of appropriate software and hardware facilities in order tocompute them in a proper and logical time. Due to this issue, sometimes, computinglasted for several days, months or years. Therefore, computer science pioneers triedto find a solution for this problem. One of the ways was to present Grid computing.In order to present high-quality service, Grid integrated separate organizations, andrepresented virtual organization. In this study, we improved reliability by usingiteration feature as well as distributing and duplicating resources. We consideredand used the first nearest resource of the second nearest resource for duplication inorder to place data. In addition, in this study, we compared our proposed methodwith other algorithms.
