SYSTEM AND METHOD FOR DECENTRALIZED CONTROL OF WIRELESS NETWORKS

摘要

System and method for decentralized control of wireless networks, made up by a set of access points (AP) that provide connection service to a set of stations (STA). The method comprises carrying out, during the start-up process, an automatic selection of the transmission channel (S7) of each access point (AP) to minimize interference, and which is based on the following information transmitted between the access points (AP) in the network:
a list of the access points (AP) that are within the range of reach of each access point (AP) in the network;the powers with which each access point (AP) receives signals from the access points within its reach;a list of preferred channels, with the lowest level of interference, for each access point (AP) in the network.

The method also enables, among other features, carrying out an automatic transmit power selection (S8).

1. System for decentralized control of wireless networks, made up by a set of access points (APs) that provide connection service to a set of stations (STA), wherein each access point (AP) comprises:
a decentralized controller, a physical layer driver, a QoS control unit, a physical layer measurement unit in charge of monitoring physical layer parameters, a physical layer control unit in charge of configuring the physical layer based on the commands sent by the decentralized controller;wherein the decentralized controllers of the various access points (AP) belonging to the wireless network are configured to, during the start-up process of the wireless network or when an access point (AP) is added to the wireless network, carry out an automatic transmission channel selection (S7) for each access point (AP) in the wireless network, wherein said selection is carried out with the aim of minimizing interference with other networks or wireless devices external to the network, and internal interference between the access points (AP) belonging to the network, and based on at least the following information transmitted between the access points (AP) in the network:
a list of the access points (AP) that are within the range of reach of each access point (AP) in the network; the powers with which each access point (AP) receives the signals of the access points within its reach; a list of preferred channels, with the lowest level of interference, for each access point (AP) in the network.
