Data replication is suitable to improve the response time, the global traffic, and the sharing of data since even in the case
of disconnection of a server. The nodes can continue to have access to replicas of data. On an Ad hoc mobile network, the
frequent partition of the network and the lack of fixed infrastructures complicate the data access and the sharing task.
In this paper, we propose a method of data replication in a mobile ad hoc network. The method is composed of two main phases.
The first phase aims at creating replicas from new data in the network and at realizing the first distribution of these replicas.
The second phase is devoted to the redistribution of replicas in order to overcome the impact of dynamic changes of topology
and to satisfy the evolution of users’ needs.
