Claim:
1. A method for managing a set of communicating objects that are distributed so that each object in the set is neighbouring at least one other object in said set so as to form a pair of neighbouring objects that are configured so as to communicate with one another, wherein, in each pair of neighbouring objects, the objects of the pair are directly placed beside one another without interposition of another of said objects, said method comprising: activating an initial object chosen among the objects in the set, and propagating, from the activated initial object, a signal to each of the other objects in the set, said propagation being configured so that each of said other objects in the set has received, at the end of the propagating, said signal from at least one neighbouring object belonging to said set at least once, wherein the propagated signal is a wake instruction, wherein, each of the objects in the set being in a passive state, a change from a passive state to an active state of the initial object is performed by the activating causing a supply of power to at least one reader of the initial object and a transmission of an electromagnetic field by said at least one reader for transmitting the wake instruction to a corresponding neighbouring object, and wherein the change from a passive state to an active state of each of the other objects in the set is performed by supplying power to a radio tag of said object in the passive state, said supply of power being caused by an electromagnetic field transmitted by a reader of a neighbouring object in the active state, said supply of power to the radio tag of said object in the passive state causing: a setup of a communication link between said reader of the neighbouring object in the active state and said radio tag of said object in the passive state, a transmission, via the communication link that has been set up, of the wake instruction by said reader of the neighbouring object in the active state, and a reception, by said radio tag of said object in the passive state, of said wake instruction causing the implementation of supplying power to at least one reader of said object in the passive state, its change to the active state, and a transmission, by said at least one powered reader, of an electromagnetic field with the aim of transmitting said wake instruction.
