We derive new
equations linking the Infrared Data Association (IrDA) data link layer (IrLAP)
throughput to the physical layer by providing the bit error rate in relation to link
distance and various physical layer parameters. Furthermore, we optimize the link by
simultaneously adapting the frame and window size. The optimum equations include the
effect of processor speed. The mathematical analysis is validated by comparison with
exact numerical methods. Analytical results presented in the paper explore the
effect of frame processing time on improving the performance of IrDA links and
identify the improvement in throughput performance by utilizing the derived optimum
values.
