Adding Node Absence Dynamics to Data Replication Strategies for Unreliable Wireless Grid Environments

To the existing data replication approaches, we add more dynamics about occasional data absence whereby files are replicated in advance in order to make all sites as suitable for job executions as possible. Occasional node or edge absence resulting in data absence is inevitable in wireless network environments. This approach offers several advantages to wireless grids, such as improved fault-tolerance, and less overhead due to dynamic data replication.
