which mode will this routing protocol running on top of, is it mesh mode, adhoc/ibss, or monitoring mode? does it work with 11n/HT(as the website mentions MIMO)?
I recall meraki somehow is using monitoring mode for its mesh algorithm. xxiao On Wed, Aug 11, 2010 at 7:03 AM, Roberto Riggio <roberto.rig...@create-net.org> wrote: > The official website is > > http://www.wing-project.org > > The website contains several info about the routing protocol.
