On the suitability of IrBurst for large data block exchange over high-speed IrDA links

This paper examines the suitability of IrBurst, a higher layer protocol recently proposed by IrDA, for large data block exchange over high-speed IrDA links. A complete analytical model for IrBurst throughput efficiency over the IrDA protocol stacks is carried out. Results are presented which reveal that IrBurst scales well for use with large data blocks and high data rates compared to the existing OBEX protocol. We also examine the effect of lower layer parameters such as IrLAP window size and frame length, and IrPHY minimum turnaround time that significantly impact the IrBurst performance. Consequently, a new automatic repeat request (ARQ) scheme is also proposed at IrLAP layer to maximize the throughput efficiency for IrBurst protocol as well as for next generation high speed IrDA links. Simulation result indicates that employment of the proposed ARQ scheme results in significant improvement of IrBurst throughput efficiency at high BER
