In this article, we consider the distributed database that can make up mobile nodes and the peer-to-peer concept. These nodes are peers and 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 transactions. The capabilities of the distributed replicated database are extended to allow mobile nodes to plan disconnection, with the capability of updating the database on behalf of the mobile node by using a fixed proxy server to make these updates during the mobile disconnection, once a mobile reconnects automatically, synchronously, and integrates into the database.
