In a Mobile Ad hoc NETwork (MANET), due to mobility, limited battery power and poor features of nodes, network partitioning and nodes disconnecting occur frequently. To improve data availability, database systems create multiple copies of each data object and allocate them on different nodes. This paper proposes Automated Re-allocator of Replicas Over MANET (ARROM) that addresses these issues. ARROM reduces the average response time of requests between clients and database servers by reallocating replicas frequently. In addition, ARROM increases the average throughput in the network.
