Abstract: The availability of multiple rates in IEEE802.11 WLANs and instability of wireless channel conditions call for data rate adaption algorithms to optimize network performance. Rate adaption is the process of assessing instantaneous channel conditions and determining the most appropriate data rate. This paper presents a relaxed probing rate adaptation scheme to determine the most appropriate instantaneous data rate for both downlink and uplink channels, especially in the case where control frames such as RTS/CTS are not available. For this goal, the proposed scheme exploits the mandatory management beacon frame, thus without requiring probing frames like RTS/CTS necessary for other so far proposed schemes. Ns-2 simulations with IEEE802.11b of the proposed scheme yield more than 100% throughput improvement in high density networks. Also, simulations show that the proposed scheme is insensitive to beacon interval.
