An efficient approach for data replication in Data Grid

Abstract

Data Grid deals with the movement of massive amount of data among storage elements. One of the challenges in Data Grids is how to reduce the average data access time by replicating data. In this article, a method for dynamic data replication called RBAAC (Replica Based Average Access Cost) is proposed which, removes files with least cost of average access time when encountering insufficient space for replication. Simulation results show that the proposed method, improved the average access time to files and network bandwidth use.
