A priority backoff algorithm applied in the wireless transmission network
LI Jing-ping
Abstract：An improved priority backoff algorithm was proposed based on the P BEB algorithm. The algo-rithm determined the contention window value by the probability g,and then executed the send action. If the data frames sent failure,the competition window value was set double according to the time slot utiliza-tion rate,with probability g settings window value after the success of the send,namely according to the adjustment of the current value of the contention window. The optimized algorithm was verified using the Infrastructure scene,the results showed that this method effectively improved the throughput,and could maintain the small access delay,reduce packet loss amount of system,and improve the performance of wireless local area network.
