Abstract: A process for keeping and/or restoring communications within a network with planned resources, the network includes stations arranged in at least one group, wherein each group is composed of at least two stations that are linked together, and the links between the at least two stations can change with a time. The process includes the following steps: associating a dummy station to one of the groups, the dummy station includes different resources, wherein the different resources are allocated to the stations in the groups; setting-up a relay station configured to keep and/or to restore communications between the stations of the groups, based on information about how a group structure evolves; and reallocating resources of the dummy station to the relay station after setting-up the relay station, based on information about how a group structure evolves.

Abstract: Data management is generally carried out by a system comprising a database. The implementation is such databases is cumbersome and entails lengthy periods of time. Furthermore, these are proprietary systems. Such systems are ill suited to open-ended and mobile systems. The present invention proposes an open method of data management that is less cumbersome, and faster to implement.

Abstract: Process and system for keeping and/or restoring communications within a network with planned resources, the said network comprising at least several stations Si distributed in subgroups, each of the said subgroups comprising at least one or several groups {Gi} each composed of at least two stations Si connected together, the link between these two stations possibly changing with time.
