Abstract
A link cost determining method including computing, by a station, a new composite data rate using a set of data rates including an average data rate, a geometric mean data rate, and a minimum data rate for data samples, computing, by the station, a pair of hysteresis thresholds for a previous composite data rate, determining, by the station, whether the new composite data rate exceeds one of the pair of hysteresis thresholds, and advertising, by the station, the new composite data rate when the new composite data rate exceeds one of the pair of hysteresis thresholds.
Claims22
A link data rate determining method performed by a station, comprising:
- computing a first data rate according to an average data rate, a geometric mean data rate, and a minimum data rate of a first array of sample data rates for a first sequence of sample time windows;
- computing a second data rate according to an average data rate, a geometric mean data rate, and a minimum data rate of a second array of sample data rates for a second sequence of sample time windows;
- and
- transmitting the second data rate based on a comparison between the second data rate and the first data rate using a hysteresis parameter.
An apparatus, comprising:
- a transmitter configured to transmit a composite data rate;
- a memory storing instructions;
- and
- a processor coupled to the transmitter and the memory to execute the instructions, the processor configured to:
- compute a first data rate according to an average data rate, a geometric mean data rate, and a minimum data rate of a first array of sample data rates for a first sequence of sample time windows;
- compute a second data rate according to an average data rate, a geometric mean data rate, and a minimum data rate of a second array of sample data rates for a second sequence of sample time windows;
- and
- transmit the second data rate based on a comparison between the second data rate and the first data rate using a hysteresis parameter.
