摘要: The IEEE 802.11 standards support multiple bit rates at the physical layer so that stations can maximize system performance by controlling transmission rate responding to conditions of underlying time-varying channels. This paper proposes a novel scheme, termed as adaptation using rate-adaptive acknowledgment (RARA). key idea RARA is regulate ACK means dictate sender adjust data rate. Compared with previous works, proposed scheme react quickly prevailing receiver-based decision while inducing marginal overhead. Simulation results show consistently outperforms other adaption schemes.
