A Survey of Dynamic Replication Strategies for Improving Response Time in Data Grid Environment

Large-scale data management is a critical problem in a distributed system such as cloud,P2P system, World Wide Web (WWW), and Data Grid. One of the effective solutions is data replicationtechnique, which efficiently reduces the cost of communication and improves the data reliability andresponse time. Various replication methods can be proposed depending on when, where, and howreplicas are generated and removed. In this paper, different replication algorithms are investigated todetermine which attributes are assumed in a given algorithm and which are declined. We provide a tabularrepresentation of important factors to facilitate the future comparison of data replication algorithms. Thispaper also presents some interesting discussions about future works in data replication by proposingsome open research challenges.
