The deployment of applications in mobile networks is hindered by limited resources and frequent network disconnection. Data replication can improve data availability in mobile networks but also introduces the challenge of adequately disseminating data without abusing user and network resources. In this context, we present CReaM, a user-Centric REplicAtion Model for mobile environment that gives priority to the users by letting them determine the amount of resources they assign to the system. In this paper, we focus on CReaM’s autonomic behavior that generates replication requests based on resource monitoring and user settings. Then, we present a simulation-based evaluation of CReaM, which shows its efficiency comparing with a periodical model; indeed, CReaM gives the same rate of data availability while it causes 50 less overhead.
