Adaptive EDCA algorithm using traffic prediction in wireless local area networks

摘要

A method comprises buffering at least one frame for a particular access class, e.g., video, 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, e.g., using a time-domain or wavelet-domain prediction algorithm, of the at least one frame in the transmission queue on the wireless medium, possibly using a known pattern of frames, e.g., an MPEG GoP; and adjusting a MAC layer time value, e.g., 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.
