Program for associating access points with stations using bid techniques
View Patent ↗The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.
1. A program product for use in an access point in a wireless communications environment including multiple access points and stations, wherein stations gain network access by associating with one or more of the access points, the program product comprising a computer readable medium having embodied therein a computer program for storing data, the computer program comprising:
logic for collecting bid messages from stations, each bid message including a parameter related to the distance between the access point and the station;
logic for sending an accept message to one of the stations from which a bid message was received, the accept message for causing the station to associate with the access point.
2. The program product of claim 1 wherein the logic for sending an accept message sends an accept message to the station whose bid message included the parameter indicating the closest distance.
3. The program product of claim 2 wherein the accept message is sent only if a maximum number of station associations has not been exceeded.
4. The program product of claim 1 further comprising logic for maintaining a table including an entry for each station from which a bid message has been received, each entry including the parameter.
5. A program product for use in an access point in a wireless communications environment including multiple access points and stations, wherein stations gain network access by associating with one or more of the access points, the program product comprising a computer readable medium having embodied therein a computer program for storing data, the computer program comprising:
logic for collecting bid messages from stations, each bid message including a parameter related to the distance between the access point and the station;
logic for maintaining a table including an entry for each station from which a bid message has been received, each entry including the parameter;
logic for sending an accept message to the station in the table having the parameter indicating the closest distance, the accept message for causing the station to associate with the access point.
