摘要

本文对802.11网络中使用定向天线引起的耳聋效应进行了性能研究。通过对天线和信道模型的不同假设，我们得出了耳聋对网络性能影响的不同结论。具体来说，在发射器和接收器之间存在信道散射的情况下，定向天线不会造成明显的耳聋和性能下降。我们还表明，即使在现有的802.11 MAC协议下，始终存在完全消除耳聋的CCA (clear-channel-assessment)阈值。

On Utilizing Directional Antenna in 802.11 Networks: Deafness Study

This paper presents a performance study of the deafness effect caused by the use of directional antenna in 802.11 networks. We show that different assumptions on antenna and channel model lead to different conclusions on the impact of deafness on network performance. Specifically, it is shown that in the presence of channel scatters between the transmitter and the receiver, directional antenna does not pose significant deafness and performance degradation. We also show that there always exists a CCA (clear-channel-assessment) threshold that eliminates deafness completely, even under existing 802.11 MAC protocols.
