Abstract
Databases of mobile ad hoc network (MANET) are stored in MANET nodes. The communication between mobile servers and clients is influenced by mobility and constrained battery energy of nodes. To enhance data availability, MANET databases create various replicas of every data object and allocate them on different mobile hosts. There are various data replication techniques that have been proposed for MANET databases. In this paper we shed some light on the MANET database concept and its utilization. We also attempt to survey the vast majority of replication techniques in MANET databases. To enhance data availability, we propose an extension of the Automated Re-allocator of Replicas Over Mobile ad hoc networks (ARROM) replication technique.
