摘要:The flexibility and diversity of Wireless Mobile Networks offer many opportunities that are not always taken into account by existing distributed systems. In particular, the proliferation of mobile users and the use of mobile Ad-Hoc promote the formation of collaborative groups to share resources. We propose a solution for the management of fault tolerance in the Ad-Hoc networks, combining the functions needed to better availability of data. Our contribution takes into account the characteristics of mobile terminals in order to reduce the consumption of resources critical that energy, and to minimize the loss of information. Our solution is based on the formation of clusters, where each is managed by a node leader. This solution is mainly composed of four sub-services, namely: prediction, replication, management of nodes in the cluster and supervision. We have shown, using several sets of simulation, that our solution is twofold: minimizing the energy consumption which increases the life of the network and better support deal with requests lost.
