Dynamic data replication improves data accessibility in mobile ad hoc networks. In our previous works, we proposed few methods to manage locations of replicas and efficiently forward access requests to the locations. In this paper, we extend these methods to adapt to an environment where data items are updated. The extended methods predict the locations of data items by storing and using the information on replica allocation at every relocation time and the logs of past data accesses. In addition, these methods give the priority to the stored information and access logs according to update and access times of the replicas
