Abstract
A method for reactivating a wireless communication network in accordance with one of the IEEE 802.11 standards is described. The communication network includes a plurality of gathering nodes, each gathering node includes at least one access-point and/or user radio-frequency interface and/or a user of a so-called backhaul wireless network associated with the communication network, which are deactivated in sending mode, A beacon frame sent by a master node of the reactivation method is propagated gradually in order to reactivate all the nodes in the network.
Claims18
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.
