Title:
ADAPTIVE EDCA ALGORITHM USING TRAFFIC PREDICTION IN WIRELESS LANS
Document Type and Number:
Japanese Patent JP2007243952
Kind Code:
A
Abstract:

To provide a system and method for increasing QoS support, in particular for VBR transmission in wireless LANs.

A method of the present invention comprises: buffering at least one frame for a particular access class in a transmission queue; performing contention-based procedures for access to a wireless medium; computing the size of the at least one frame in the transmission queue; predicting the size of at least one future frame expected to arrive in the transmission queue during transmission, using a time-domain or wavelet-domain prediction algorithm, of the at least one frame in the transmission queue on the wireless medium using a known pattern of frames; and adjusting a TXOP based on the size of the at least one frame in the transmission queue and the predicted size of the at least one future frame.
