Abstract

In this article, we consider the distributed database that can make up mobile nodes as well as peer-to-peer concepts. These nodes and peers may be replicated both for fault tolerance (dependability), and to compensate for nodes that are currently disconnected. Thus we have a distributed replicated database, where several sites must participate in the synchronization of a transaction. The capabilities of the distributed replicated database are extended to allow mobile nodes to plan for a disconnection, with the capability of update, and for the database—on behalf of mobile node by using fixed proxy server—to make these updates during the mobile disconnection. Once a mobile reconnects, it automatically synchronizes and integrates into database.
