Experimental setup

As shown in Figure 1, we used two wireless clients at two different locations corresponding to two different signal conditions. The ``Good'' client $G$ laid in an area of good AP coverage, in terms of SNR (the 40 dB-line), while the ``Bad'' client $B$ laid in an area of bad AP coverage (the 15 dB-line). We also had three wireless sniffers ($T$, $U$ and $V$) capturing the wireless traffic between Source, Sink, and the AP. Sniffer $T$ was placed adjacent to the AP, while $U$ and $V$ were placed.
