Fairness provision via controlling a transmission opportunity window in a wireless mesh network

摘要

The invention allows fairness provision in wireless mesh networks with respect to the data rate that stations communicate. A fairness metric is obtained during a mesh profile negotiation performed in order for a wireless station to join a wireless mesh network. Predetermined mesh transmission parameters of the wireless station are sent to previously joined wireless stations in a predetermined neighborhood of the wireless station. From the previously joined wireless stations their respective predetermined mesh transmission parameters are received. In response to a first predetermined event, a transmission opportunity window is determined for the wireless station based on the obtained fairness metric, the predetermined mesh transmission parameters of the wireless station, and the predetermined mesh transmission parameters of the previously joined wireless stations.

1. A method of fairness provision via controlling a transmission opportunity window, comprising:
obtaining a fairness metric during a mesh profile negotiation performed in order for a wireless station to join a wireless mesh network; sending predetermined mesh transmission parameters comprising a currently communicated average data rate and a last used transmission opportunity window of the wireless station to previously joined wireless stations in a predetermined neighborhood of the wireless station; receiving from the previously joined wireless stations in the predetermined neighborhood of the wireless station their respective predetermined mesh transmission parameters comprising a currently communicated average data rate and a last used transmission opportunity window of the respective wireless station; and in response to a first predetermined event, determining a transmission opportunity window for the wireless station based on the obtained fairness metric, the predetermined mesh transmission parameters of the wireless station, and the predetermined mesh transmission parameters of the previously joined wireless stations, and based on maximizing a sum of ratios of an instantaneous data rate and the currently communicated average data rate for each wireless station.
