| network type | 802.11 infrastructure |
| environment | We collected data from a wireless network deployed at a recently concluded 62nd
Internet Engineering Task Force (IETF) meeting held in Minneapolis, MN.
The meeting was held March 6-11, 2005 and was attended by 1138 participants.
Almost all of the participants used laptops or other wireless devices. |
| network | The IETF network was comprised of 38 Airespace2 1250 access
points (APs) distributed on three adjacent floors. Each Airespace
AP supported four virtual APs. A virtual AP is a logical AP that
exists within a physical device and enables the wireless LAN to
be segmented into multiple broadcast domains. This provides the
ability to map multiple Extended Service Set Identifiers (ESSIDs)
to multiple Basic Service Set Identifiers (BSSIDs). Thus, at the
IETF, a total of 112 APs (38 physical APs x 4 ESSIDs per physical
AP) were available for utilization. |
| collection | The method adopted to collect information from the wireless portion
of the IETF network is referred to as wireless network monitoring
[yeo-framework] or vicinity sniffing. In order to capture network frames
that were transmitted by access points and user devices in the network,
we chose to place three laptops (wireless network sniffers)
at a single vantage point in the network. The location was strategically
selected so that our sniffers could overhear and record the maximum
possible information. |
| sanitization | The data traces have been anonymized using tools from the CRAWDAD project
(the tool used for anonymizing dartmouth/campus/tcpdump). In other words,
the IP and MAC addresses have been hashed and the frame payloads have been removed. |

Network Performance Analysis
|
| methodology | We performed vicinity sniffing (or wireless monitoring) using three
IBM R32 Think Pad laptops. Each laptop was equipped with a Netgate
2511 PCMCIA 802.11b radio. The radios were configured to capture frames
in a special operating mode called the RFMon mode. The RFMon
mode enables the capture of regular data frames as well as IEEE
management frames that are transmitted on a single channel. In
addition, the RFMon mode records information for each captured
frame. This information includes the send rate, the channel used
for frame transmission, and the signal-to-noise ratio (SNR) of the
frame as received by the sniffer.
Because the Airespace APs were expected to switch between the 802.11b
1, 6, and 11 channels, our laptops were each configured to sniff
on one of the three different channels for the duration of the session.
The frames were captured using the sniffer utility, tethereal.
The snap-length of the captured frames was set to 250 bytes in order
to capture only the RFMon, MAC, IP, and TCP/UDP headers. |
