Detailed Description

trace sink for wifi device that mimics madwifi's athstats tool.

Introspection did not find any typical Config paths.

The AthstatsWifiTraceSink class is a trace sink to be connected to several of the traces available within a wifi device. The purpose of AthstatsWifiTraceSink is to mimic the behavior of the athstats tool distributed wih the madwifi driver. In particular, the reproduced behavior is that obtained when executing athstats without parameters: a report written in text format is produced every fixed interval, based on the events observed by the wifi device.

Differences with the "real" athstats:


Attributes

  • Interval: Time interval between reports
    • Set with class: ns3::TimeValue
    • Underlying type: Time –9223372036854775808.0ns:+9223372036854775807.0ns
    • Initial value: +1000000000.0ns
    • Flags: construct write read

No TraceSources are defined for this type.
Size of this type is 80 bytes (on a 64-bit architecture).
