Abstract
A modem of a smart electricity meter obtains, following a registration in the powerline communication network of the ad hoc type, routing information and encryption information, by exchanges of messages in the powerline communication network. The smart electricity meter saves in non-volatile memory the routing information and the encryption information, the routing information being saved in association with information representing an instant at which the backup is made. At the time of a subsequent re-registration of the smart electricity meter following a disconnection of the powerline communication network, the smart electricity meter retrieves the routing and encryption information previously saved in the non-volatile memory, updates it by deleting any route information that is no longer valid, and uses it to communicate in the powerline communication network.
