“…Furthermore, the propagation delay is omitted since it has a marginal impact on 1 Gb/s Giga-IR systems. The typical infrared link length is limited to a few centimeters due to the existence of a docking station [1] and the propagation delay amounts to 10-30 ns. As a result, it can be ignored in all practical cases, where the transmission of the physical layer overheads and/or link turnarounds take at least one order of magnitude longer to complete.…”

“…The advantages of shortrange infrared links have led to their standardization by the infrared data association (IrDA), which actively maintains a comprehensive list of standards for the infrared physical layer, as well as the overlying protocol stack that is used to control the link operation and facilitate the communication between infrared devices. The latest IrDA Giga-IR standards for short-range optical wireless systems specify bit-rates that exceed 1 Gb/s, and even higher rates are expected in the systems of the near future [1][2][3]. Such capacity has been made feasible following a long series of standardization and research efforts that optimized the operation of both the physical layer and the overlying protocol stack [4][5][6][7][8][9].…”

We present an analytical model for dimensioning the buffering requirements of the link-layer in half-duplex Gb/s infrared links. Our model takes into account both physical layer parameters, including the bit-error-rate and the turnaround time of the link, and link-layer parameters, including the protocol window and frame size, in order to calculate the utilization efficiency of the infrared link as a function of the buffer size. We utilize the model to establish the buffer size that is required to achieve acceptable efficiencies for a broad range of standardized infrared link and link-layer protocol configurations. Our analysis shows that it is possible to optimize the link-layer window and frame size in order to achieve maximum efficiency for any given buffer size and link configuration, and we provide analytical relations for the buffer-constrained optimal window and frame size.
