摘要

IEEE802.11 RTS/CTS握手，以避免与隐藏终端传输的数据包冲突。虽然RTS/CTS握手有效地减少了与隐藏终端的数据包冲突，但也增加了IEEE802.11的传输开销。本文讨论了RTS/CTS握手引起的IEEE802.11传输开销，并在隐藏终端存在的基础上提出了一种新的自适应RTS/CTS控制方法，以减轻IEEE802.11的传输开销。计算机仿真结果证实了该方法在饱和交通环境下提高了吞吐量性能。

Throughput Improvement of IEEE802.11DCF with Adaptive RTS/CTS Control on the Basis of Existence of Hidden Terminals

IEEE802.11 RTS/CTS handshake to avoid a packet collision with the transmissions from hidden terminals. Although RTS/CTS handshake effectively reduces packet collisions with hidden terminals, it also increases transmission overhead of IEEE802.11. In this paper, we discuss transmission overhead of IEEE802.11 induced by RTS/CTS handshake, and propose a new adaptive RTS/CTS control method on the basis of existence of hidden terminals, for mitigating transmission overhead ofIEEE802.11. Results from computer simulations confirm that our proposed method improve throughput performance in around the saturated traffic environment.
