Method for propagating an event arising on a device of a structured radiofrequency communication network comprising a plurality of devices, characterized in that frames are used, each frame comprises: - an information item, termed a configuration information item, making it possible to indicate to a device receiving the frame that it must reconfigure itself so as to operate in the guise of router so as to propagate frames that it receives through the use of a routing table, - a device identifier whose value defines whether the device that sent the alert frame originated the propagation of the alert frame in the network, and - an information item, termed an event information item, indicating that the event arises on the device which originated the propagation of the frame in the network or whether this event no longer arises on this device; the method being executed by at least one device, which: - reconfigures itself so as to operate in the guise of router subsequent to the detection of the event by this device, - sends, once reconfigured as a router, a frame, termed an alert frame, in which the value of the device identifier defines that this device originated the propagation of the alert frame in the network and the event information item indicates that the event arises on this device, and - when another device receives an alert frame (8,9), this other device reconfigures itself so as to operate in the guise of router and sends, once reconfigured as a router, another alert frame in which the value of the device identifier defines that this other device did not originate the propagation of the frame in the network and the event information item indicates that the event arises on the device which originated the propagation of the frame in the network, and in that, once reconfigured as a router, each device is intended to propagate signal frames that it receives, through the use of a routing table. - an information item, termed a configuration information item, making it possible to indicate to a device receiving the frame that it must reconfigure itself so as to operate in the guise of router so as to propagate frames that it receives through the use of a routing table, - a device identifier whose value defines whether the device that sent the alert frame originated the propagation of the alert frame in the network, and - an information item, termed an event information item, indicating that the event arises on the device which originated the propagation of the frame in the network or whether this event no longer arises on this device; - reconfigures itself so as to operate in the guise of router subsequent to the detection of the event by this device, - sends, once reconfigured as a router, a frame, termed an alert frame, in which the value of the device identifier defines that this device originated the propagation of the alert frame in the network and the event information item indicates that the event arises on this device, and - when another device receives an alert frame (8,9), this other device reconfigures itself so as to operate in the guise of router and sends, once reconfigured as a router, another alert frame in which the value of the device identifier defines that this other device did not originate the propagation of the frame in the network and the event information item indicates that the event arises on the device which originated the propagation of the frame in the network,
