The replication mechanism is one of the existing solutions used to increase data availability in mobile environment. It must be applied intelligently to be suitable for dynamic ad hoc environment. Our research work focused on presenting a fully decentralized replication model that centers on the user desired. The core of the replication model is a component that is responsible of monitoring the node’s status. It helps the other components to take replications decision like when to start the replication process or where to place the replicas. This component makes the replication model suitable for mobile environment because the replication decision is taken locally depending on user desired without negotiation with nodes in neighborhood.
