Abstract
A tool for selectively printing out header fields/flags from either live or recorded 802.11 traffic.
This tool is able to select out header fields/flags from either live or recorded 802.11 traffic. Tcpdump and Tethereal have limited flexibility to tease out specific fields without printing out the entire packet.

File :
wifi_parser_20071105.tar.gz
Releasedate :
2007-11-05
Change :
updated the types for ISO C compatibility (i.e., u_int instead of uint)
Website :
http://www.crawdad.org/tools/process/pcap/wifi_parser
Keyword :
802.11 frames 802.11 packet trace tcpdump signal strength
Output :
An example use of this tool is to process large capture files and then perform mathematical analysis on the values contained in the fields. Here is an example output of the tool in use: %./wifi_parser -p -r mapreceiver-mapsampler1-100000.cap -s aibstq -c 100 WiFi frame parser starting... 1142538621.941872 27 0_0_0_0_0_0_0_0 bssid: 000b868138b0 s: 000b868138b0 seq: 2290 1142538621.942814 27 0_0_0_0_0_0_0_0 bssid: 000b868138b1 s: 000b868138b1 seq: 2291 1142538622.396284 16 0_1_0_0_0_0_0_0 bssid: 000b868139c8 s: 0009e9b7400a seq: 3574 1142538622.436236 16 0_1_0_0_0_0_0_0 bssid: 000b868139c8 s: 0009e9b7400a seq: 3581 1142538622.439394 15 0_1_0_0_0_0_0_0 bssid: 000b868139c8 s: 0009e9b7400a seq: 3584 1142538622.456254 17 0_1_0_0_0_0_0_0 bssid: 000b868139c8 s: 0009e9b7400a seq: 3594 1142538622.460492 17 0_1_0_0_0_0_0_0 bssid: 000b868139c8 s: 0009e9b7400a seq: 3598 1142538622.461425 18 0_1_0_0_0_0_0_0 bssid: 000b868139c8 s: 0009e9b7400a seq: 3599 1142538622.496193 19 0_1_0_0_0_0_0_0 bssid: 000b868139c8 s: 0009e9b7400a seq: 3600 1142538622.498403 19 0_1_0_0_0_0_0_0 bssid: 000b868139c8 s: 0009e9b7400a seq: 3602 1142538622.501529 19 0_1_0_0_0_0_0_0 bssid: 000b868139c8 s: 0009e9b7400a seq: 3605 1142538622.503735 19 0_0_0_0_0_0_0_0 bssid: 000b868139c8 s: 000b868139c8 seq: 3606

These datasets are part of Community Resource for Archiving Wireless Data (CRAWDAD). CRAWDAD began in 2004 at Dartmouth College as a place to share wireless network data with the research community. Its purpose was to enable access to data from real networks and real mobile users at a time when collecting such data was challenging and expensive. The archive has continued to grow since its inception, and starting in summer 2022 is being housed on IEEE DataPort.
