We consider a mobile replicated database that consists of several mobile nodes, each containing a replicated copy of a common database. The nodes are interconnected through a wireless network along with a fixed server which retains the primary copy of the database. In this work, we have proposed an efficient database synchronization algorithm — Mobile Replicated Database Management Synchronization...
