Abstract

In a Mobile Ad-hoc Network (MANET), due to the mobility and energy limitations of nodes, disconnection and network partitioning occur frequently. In addition, transactions in many MANET database applications have time constraints. In this paper, a Data REplication technique for real-time Ad-hoc Mobile databases (DREAM) that addresses all these issues is proposed. DREAM is prototyped on laptops and PDAs and compared with two existing replication techniques using a military database application.
