Abstract
A retry algorithm determines the maximum number of transmissions and retransmissions that may be attempted for the frame in the head of a transmit queue or transmit buffer that needs to be transmitted across a communications link. The algorithm attempts to achieve a constant delay for each packet in frame by taking into account the number of frames residing in the transmit queue, the number of transmit opportunities elapsed between the arrivals of two successive frames in the transmit queue s, as well as the buffering capabilities of both the transmitting and receiving sides. The transmission and retransmission control technique provides for a way of managing the TX and RX buffers with a size that is suitable for the application being used and the underlying transport network. The number of retries is adapted to incoming and outgoing data rate changes in order to provide a fixed delay wireless link transport and maximize effective channel utilization.
