WLC10-3: IrSimple Modeling and Performance Evaluation for High-Speed Infrared Communications

IrSimple is a high-speed Infrared communications protocol to provide simple and instant wireless communications between mobile devices and digital home appliances. This paper provides a mathematical model with which we derive a simple equation for IrSimple throughput efficiency. Based on this model, we compare the performance of IrSimple protocol with the existing IrDA protocol for exchanging digital contents at high data rates. Results are presented which reveal that IrSimple protocol scales well for use with high data rates compared to the existing OBEX protocol. The significance of parameters such as IrSMP block size and link minimum turnaround time on IrSimple performance is also examined. Finally, an enhancement of existing error control scheme to provide robustness for IrSimple protocol at high bit error rates and an improvement in flow control to reduce redundant data retransmissions are presented.
