CRAWDAD tools/collect/802.11/wrapi_plus

A tool for monitoring wireless statistics in real-time.

WRAPI+ is a tool to monitor wireless statistics, including received signal strength, transmitted frame count, and failed frame transmissions and acknowledgments on a Windows XP end hosts' IEEE 802.11b/g network device. WRAPI+ was built upon the freely available WRAPI C++ library.

Keyword :

802.11 RFMON signal strength

Output :

MAC Layer Statistics (e.g., RSSI, TransmittedFragmentCout, RetryCount, etc)

Parameters :

Output file name

Usage :

1)Before you run wrapi.exe, you need to stop "Wireless Zero Configuration Service". by typing these two command at the command prompt "net start ndisuio" and "net stop WZCSVC" 2) wrapi.exe [filename] It will generated two logfiles: [filename]_log.dat: the Mac Layer Statistics Data. [filename]_en.dat : Key the AP's Information. If there exist multiple APs. It will recorder all the AP's Mac address. However, sometime it would log a fake AP'MAC. If no parameter is given, it will generate logfile names use the current date for you such as "20041025153112.dat" and put it in the same directory.

Algorithm :

WRAPI+ is an application built upon the freely available C++ library named WRAPI10 that provides function calls to gather wireless statistics in Windows XP. When run on an end-host, WRAPI+ periodically (every 500 ms, by default) reports and logs IEEE 802.11 network interface statistics that includes received signal strength, transmitted frame count, and failed frame transmissions and acknowledgments. WRAPI+ is provided with source code to maximize reuse and enable measurement customization.

Limitation :

1) Only works with some chipsets, For example: Net Gear WG511g v1 card. Lucent ORiNOCO wireless cards, Cisco Aironet cards (340 and 4800 series), Compaq and Dell in-built wireless cards, (Dell could not get Fail Count) Linksys cards. (not sure)
