Abstract: Determined is a topology of a communication network composed of a plurality of nodes connected or not respectively to at least one item of equipment, one of the nodes, referred to as the root node, being connected to an external network. A service class is determined for each node, from each node, information is obtained representing the quality of the link between the node and other nodes, for each link, parameters representing the quality of the link are calculated, the nodes are classified according to the service class thereof and according to the number of links making up the path that separates them from the root node, for each node and according to the classification, the possible paths connecting the node to the root node are determined, a score is calculated for each path determined, the path is selected for the node having the best score.

Abstract: A method and device for protecting a local area network including nodes allowing an extension of wireless communication coverage in order to increase the range of the local area network by coordinating a plurality of access points integrated in the nodes, the nodes being interconnected by a backhaul subnetwork, each node in the backhaul subnetwork transmitting at least one wireless network referred to as a fronthaul network, the method includes the steps of: detecting a connection of a station by a cable connection to a network switch included in the local area network, the network switch being connected to the backhaul subnetwork by a cable connection, establishing secure connections between each node if the connection of the station by a cable connection to the network switch is detected, managing the nodes of the network connected to the network switch with filtering rules applied to the data received by the nodes.

Abstract: To pair a plurality of stations with a wireless access point, the wireless access point establishes a multiple pairing. The wireless access point includes, in broadcast beacon frames, a notification of triggering of multiple pairing, during a declaration period of predefined maximum duration. The wireless access point receives, during the declaration period, requests for participation in the multiple pairing coming from said stations. When the declaration period expires, the wireless access point implements individual pairings in turn with each of the stations in question.

Abstract: A method for determining eligibility for a handover of a client node of a distributed communication network that includes a plurality of gathering nodes. The client node is associated with one level among a plurality of levels. The method includes determining a connection quality indicator and determining a connection quality threshold dependent on the level. If the connection quality indicator compared with the threshold indicates a poor relative quality of the connection then incrementing the level or executing a handover method, otherwise if, and as long as, the connection quality indicator compared with a threshold determined according to the level immediately below the level associated with the client node indicates a better connection quality, then decrementing the level.

Abstract: This method for managing the connection of a user equipment item to a distributed wireless communication network includes the following steps: sorting access nodes of the distributed wireless communication network into different groups as a function of a primary indicator representative of their quality of connection to a distributed wireless communication network root node and, for at least one access node included in a selected group: determining a secondary indicator representative of a quality of connection of the user equipment item to the access node. If, for each access node included in the selected group, the secondary indicator is strictly greater than a threshold, the steps are repeated with another group containing access nodes having a lower quality of connection to the root node.

Abstract: A method for pairing a terminal with an access point in a wireless communication network is described. The network comprises a plurality of access points that are centrally coordinated by a manager device. The method comprises the following steps executed by at least one access point: receiving a first message comprising information indicating that said terminal wishes to pair with said access point; sending a second message to said manager device, said second message comprising information indicating that said terminal wishes to pair with said access point; adding, in at least one beacon frame of said access point, information indicating that a pairing session is active, only on receipt of a message from said manager device notifying said access point to engage a pairing session with said terminal; and pairing said access point and said terminal.
