Summary

This paper proposes a new Markov model to analyze the throughput of the RCP (Reception Control Protocol) [1]. The model combines the service time of the 802.11b MAC layer protocol and the transmission characteristic of the RCP congestion window. Furthermore, in order to improve the throughput of WLAN (Wireless LAN) we introduce a mechanism called DREQs (Delayed REQs) in the RCP. Although this mechanism is similar to delayed ACK of TCP, it has higher robustness in wireless networks. We have extended our analysis to the throughput of DREQ-REP and proved the DREQs mechanism can improve the performance of RCP. The simulation results not only validate our throughput model but demonstrate that the DREQs can effectively improve the performance of RCP in WLAN.
