Abstract

Problem statement: In Mobile grid, the mobile devices can be effectively incorporated in to the Grid. It enables both the mobility of the users requesting access to a fixed grid and the resources that are themselves as part of the grid. There are number challenging issues for mobile grid; such as connectivity, availability, maintainability, consistency and fault tolerance. This study addresses the issue of data replication solution that maintains consistency, which improves the availability of replicated data in a small scale mobile grid environment. Approach: In this study we propose a structural design that improves the availability in a mobile grid environment by placing the replica in an optimized manner so that the performance of the mobile grid environment can be improved and a multi agent based approach to maintain the consistency between the replicated data effectively by propagating the latest updates intelligently. Results: The study presents the results depicting the advantageous of using agents in data replication, which includes reduction in data communication cost under different circumstances like change in mobility of nodes, read write ratio of nodes and replication schema. Conclusion: The proposed method will select the optimum number of locations to place the replica such that the maintenance overhead such as update propagation, consistency maintenance, storage cost and communication cost will be reduced.
