In order to monitor a large-dimension environment, a plurality of emitters is provided and a central emitter (1) allocates, to each of the emitters, an identifier allowing the identification of each emitter in the environment, a parent identifier that can transmit information to an emitter, and a child identifier which is the furthest away, the identifier of which has the largest value towards which an emitter can transmit. When an alert indicating a change in the environment is generated by one of the emitters and sent to the central emitter, said identifiers allow an optimum and secure transmission towards the central emitter, and likewise, when a message is sent from the central emitter towards an emitter. |
