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 replication technique, which efficiently reduces the cost of communication and improves the data reliability and response time. Various replication methods can be proposed depending on when, where, and how replicas are generated and removed. In this paper, different replication algorithms are investigated to determine which attributes are assumed in a given algorithm and which are declined. We provide a tabular representation of important factors to facilitate the future comparison of data replication algorithms. This paper also presents some interesting discussions about future works in data replication by proposing some open research challenges.
