Abstract: A regulation method intended to reduce congestion in a mesh powerline communication network that includes a plurality of node devices, a route discovery request being sent by a source node device and requests being relayed by intermediate node devices to a destination node device. The regulation method is implemented by an intermediate node device, which can receive a plurality of route discovery requests, and includes the steps of: detecting a congestion situation when a number of requests received over a time window of predefined duration is above a predefined first threshold; identifying requests as important when the number of any one request received over the time window of predefined duration is above a second predefined threshold; and relaying solely requests identified as important.

The intermediate node device is able to send messages on at least one frequency band by powerline and over a radio channel, and by means of the intermediate node device: detects a congestion situation, identifies route requests as being important, relays only copies of the important relay requests on a frequency band and over the radio channel, and relays copies of the non-important route requests on a frequency band or over the radio channel.

Abstract: A method and device for transmitting a message from a first node device to a second node device, the devices using powerline communications. The first node device is able to send and receive fragments of the message on at least one frequency band using powerline communications and over a radio channel. The first node device, prior to the transmission of the fragment: estimates, for at least one frequency band, the theoretical duration of transmission of the fragment on the frequency band, and for the radio channel, the theoretical duration of transmission of the fragment on the radio channel, obtains, from a database, the result of integration of the degree of occupation of the frequency band and of the result of integration of the degree of occupation of the radio channel, selects, from the results of integration, the frequency band or the radio channel and transmits the fragment.

Abstract: A method for transmitting a message from a first node device to a second node device in which the second node device belongs to network neighborhood of the first node device. The first and second node devices belong to an electrical supply network using powerline communications. The first node device begins by fragmenting the message into at least a first fragment and a second fragment. Next it associates a first frequency band of a set of frequency bands with the first fragment and a second frequency band with the second fragment, the first and second frequency bands being different. It then transmits each first and second fragment on the frequency band with which it is associated.
