1. A method for reactivating a wireless communication network in accordance with one of the IEEE 802.11 standards comprising a plurality of gathering nodes organised in a parent/child hierarchy, at least one gathering node in said communication network, referred to as the current node, comprising an access-point radio-frequency interface and a user radio-frequency interface of a so-called backhaul wireless network associated with the communication network, said access-point and user radio-frequency interfaces of said backhaul network being deactivated in sending mode, the method being executed by said current node and comprising:
receiving a first beacon frame comprising state information indicating a reactivation; and
a) putting in memory state information on said current node in order to indicate that a reactivation is under way;
b) reactivating, for said current node, all of its access-point and user radio-frequency interfaces of the backhaul network;
c) broadcasting a second beacon frame comprising state information indicating a reactivation;
d) pairing with a parent node and, in the case where said current node has child nodes, waiting until said child nodes pair with it and checking that said child nodes are reactivated;
updating an internal state indicating that said current node is reactivated.
