MANET has a collection of autonomous mobile nodes that can move freely and unpredictably to form a temporary network, without the need of any infrastructure. In a mobile ad hoc network, the mobile nodes will have the characteristics of mobility and constraints in resources. Since, the mobility is high, the nodes may move fast and randomly, which lead to network partitioning. The resource constraints lead to a big problem as decrease in performance and the network partitioning leads to poor data accessibility. To improve the data accessibility many data replication techniques have been proposed to minimize performance degradation caused by network partitioning in a mobile ad hoc network.
