1. A method for dynamically monitoring a group of wirelessly communicating mobile entities, characterized in that it comprises:
- assigning each entity a unique identifier;
saving within a referring entity the list of the identifiers of all of the entities in the group;
determining, for each entity, a vicinity with a predetermined radius;
repeatedly, for each entity in the group;
detecting the other entities located in its vicinity;
transmitting a message to the detecting entities, said message containing at least the identifier of the entity, to be relayed to the referring entity;
collecting, within the referring entity, the messages relayed to it;
creating a list of identifiers contained within the messages;
comparing this list to the saved list;
if the lists are identical, determining the cohesive group;
otherwise, determining the non-cohesive group.
