The invention relates to a method for monitoring a group of objects and to an arrangement of the objects resulting therefrom. According to this method, each object (1) of the group (2) to be monitored is provided with a radio node (4) of a self-networking radio network, each radio node (4) within the group (2) having, selecting itself or receiving a unique identification. The radio nodes (4) of the group (2) automatically reveal themselves at a starting time and network with one another. From the starting time, the radio nodes (4) of the group (2) monitor themselves and notify each other of at least one specified change in the mutual situation. When notifying or recognizing a specified change, at least one of the radio nodes (4) conveys information concerning this change to a monitoring unit (6) and/or controls an alarm transmitter (7) for activating an alarm. The inventive method makes it possible to easily reduce the risk of theft of objects from a group, particularly of bundled products during the distribution process.

L'invention concerne un procédé servant à surveiller un groupe d'objets, ainsi qu'un ensemble d'objets résultant de ce procédé. Selon ce procédé, chaque objet à surveiller (1) du groupe (2) est muni d'un noeud radio (4) d'un réseau radio à établissement automatique, chaque noeud radio (4) à l'intérieur du groupe (2) présentant, sélectionnant lui-même ou recevant une identification univoque. Les noeuds radio (4) du groupe (2) se détectent automatiquement à un instant initial et se mettent en réseau. A partir de cet instant initial, les noeuds radio (4) du groupe (2) se surveillent et se signalent au moins une modification définie dans leur situation réciproque. En cas de signalement ou de détection d'une modification définie, au moins l'un des noeuds radio (4) transmet des informations sur la modification à une unité de surveillance (6) et/ou provoque le déclenchement d'une alarme par un générateur d'alarme (7). Le procédé selon l'invention permet de réduire de manière simple le risque de vols d'objets dans un groupe, notamment de produits dans un lot pendant le processus de distribution.
