I've not found any documentation of either DAWN or Usteer apart from hints that their purpose is to direct WiFi clients to the most appropriate AP or router. Is there a feature list and requirements list for either? Or a technical comparison between the two?
i guess you went through Dawn: a decentralized wireless controller and know @IanC did a tremendous work documenting and improving DAWN https://github.com/Ian-Clowes/DAWN. there are great deal of explanation about DAWN in his git repo.
usteer is not really documented am afraid.
