Executive Summary

In mobile environments, mobile device users access and transfer a great deal of data through the online servers. In order to enhance users' access speed in a wireless network, decentralizing replicated servers appropriately in the network is required. Previous work regarding this issue had focused on the placement of replicated servers along with the moving paths of the users to maximize the hit ratio. When a miss occurs, they simply ignored the file request. Therefore, the authors suggest a solution to take care of such a miss by sending a file request to a replicated server nearby in the network.
