A method implemented by a processing unit of a first communicating electronic device further including a data memory, first communication means providing nearby wireless communication with any other communicating electronic device situated within communication range within a cluster comprising a plurality of communicating electronic devices, said memory and said communication means cooperating with said processing unit, the data memory storing the value of an identifier dedicated to the first communicating electronic device and a register arranged to include the current value of an identifier of a communicating electronic device acting as a cluster head, said method including a step for sending a service message to the device acting as cluster head, and being further comprising:
- a step prior to the sending of the service message for generating and sending, via the first communication means, a verification message (MAS) for belonging to the cluster, said message encoding:
- i. the value (MAS-1) of the identifier of a second communicating electronic device as identifier of the communicating electronic device recipient of said verification message (MAS) for belonging to the cluster;
- and
- ii. the value (MAS-2) of the identifier of the first device as identifier of the communicating electronic device that is the source of said verification message (MAS) for belonging to said cluster.
