A wireless electronic detonator includes a primary source of energy and at least one functional module. A power switch is disposed between the primary source of energy and the functional module to connect or disconnect the functional module and the primary source of energy. A controller controls the power switch and includes an optical receiver to detect and demodulate a light signal emitted by a control console, The controller generates a control signal according to the demodulated light signal to at least control the power switch. A wireless detonation system includes the wireless electronic detonator and the control console configured to emit a light signal, and method for activating the wireless electronic detonator.

The method for managing a set () of communicating objects (), which are distributed such that each object () in the set () is neighboring at least one other object () in said set () so as to form a pair of neighboring objects that are capable of communicating with one another, has the following steps: activation (E) of an initial object () chosen among the objects () in the set (); propagation (E), from the activated initial object (), of a signal to each of the other objects in the set, said propagation being configured such that each of said other objects in the set has received, at the end of the step of propagation (E), said signal from at least one neighboring object belonging to said set at least once.
