METHOD FOR DYNAMICALLY MONITORING A GROUP OF MOBILE ENTITIES

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.
