| methodology | The first method was wireless monitors. We placed five PCs, each
with three Netgear WAG311 wireless adapters, near the APs. Each
monitor listened on all three active channels, using external antennas
which we placed at least a foot apart from each other to avoid
interference. Multiple monitors were within the range of each AP
to provide information on the spatial diversity of transmission and
reception.
We logged all observed activity using tcpdump, capturing 802.11
control and management packets as well as data packets and writing
complete packets to disk. The PHY information includes a receive
signal strength indicator (RSSI) and the transmission rate.
The MAC information is the entire 802.11 frame header and CRC.
We also customized our MADWiFi driver to log reception errors
that provide information on periods when transmissions were detected
but not correctly decoded.
Monitor channels (primarily) are as follows: ath0=1, ath1=8, ath2=11.
Exception is that the APs switched from channel 8 to channel 6 on Wednesday
morning (9/1/2004); kalahari switched ath1 to channel 6 Wednesday at 12:24 pm,
and sahara, chihuahuan, and sonoran switched ath1 to channel 6 Friday at 8:30 am. |
| error | 1. We used the noise field of the prism frame to encode
error status of frames, so be sure to filter down to only those frames
with noise values of zero. others are errored packets
(corrupt or not fully received).
2. The clocks on different machines were not synchronized;
chihuahuan's clock is the most accurate |
| note | three of the ath2 traces (chihuahuan, mojave, and sonoran)
were very large. the split command was used to break them up into
1G segments to allow sharing them online. you will need to
cat the segments of each before unzipping. |
