SYSTEM AND METHOD FOR DECENTRALIZED CONTROL OF WIRELESS NETWORKS

AOIFE SOLUTIONS, S.L., C...

11. A method for decentralized control of a wireless local area network, the wireless local area network comprising a plurality of access points that provide connection service to a plurality of stations, the method comprising:each access point in the wireless local area network sequentially scanning the channels, during a start-up process of the local area wireless network or when an access point is added to the wireless local area network, to detect beacons transmitted by other access points thereby building a plurality of channel maps, each channel map containing network structure information of each access point of the wireless local area network whose transmitted beacons are received, a power with which the beacons are received;
inter-transmitting among the plurality of the access points of the wireless local area network, the plurality of channel maps such that each access point in the wireless local area network gathers and shares all of the plurality of channel maps from all of the plurality of access points of the wireless local area network;
each access point locally computes a channel selection for all of the plurality of access points of the wireless local area network, wherein said channel is selected based on the all of the plurality of channel maps containing network structure information gathered and shared by each access point and using a criteria to minimize interference between the access points of the wireless local area network and minimize interference with other networks or wireless devices external to the wireless local area network; and
assigning a transmission channel based on the locally computed channel selection for each access point of the plurality of access points of the wireless local area network.
