Patent number: 11863424Abstract: Selecting a communication route between a first and a second node device of a mesh electrical supply network using powerline and/or radio-frequency communications is described. A route cost is obtained for each possible communication route. A communication route of the lowest route cost is selected. For a given route, the route cost is the sum of the link costs between successive node devices on the route, the link cost between two successive node devices is a weighted sum between a maximum value from a link cost in a forward direction and a link cost in a backward direction and a ratio between a number of active routes and a maximum number of active routes. A link cost in a given direction depends on the cost of the link, in the given direction, calculated for each frequency band of frequency bands used by the two successive node devices for communicating.Type: GrantFiled: June 25, 2021Date of Patent: January 2, 2024Assignee: SAGEMCOM ENERGY & TELECOM SASInventors: Jérôme Barois, Ziv Roter, Julien Barthes
