Abstract:
1. A method for monitoring a group of objects, comprising: providing each object to be monitored with a radio node of a self-networking radio network; assembling a plurality of the objects provided with the radio nodes together to form the group, whereby each radio node within the group has a unique identification assigned to it, or receives a unique identification selected in coordination with the other radio nodes of the radio network; automatically revealing individual radio nodes of the group at a starting time so that the plurality of radio nodes network with one another and initialize a mutual spatial position of the objects within the group; monitoring the individual radio nodes of the group from the starting time to detect a change in the mutual spatial position and conveying at least one specified change in the mutual spatial position from at least one radio node that recognizes the change to another radio node; and conveying information concerning the change from the at least one of said radio nodes to one of a monitoring unit or an alarm transmitter for activating an alarm.
