Hey,
Yes we thought about that too (actually that was my first idea),
but this might lead to inconsitency as not all hosts will get an update
when a node moves but only those nodes which are on the way. Furthermore
the packet reading (and cache updating) increases latency to forwarding.
A solution might be to increase the rate in which batman-packets are
sent (because then host announcement goes with them), or create a new
packet type for announcement and send these more often. Both brings us
much more noise in the mesh.
I wonder if having a wifi-mesh is good for (hard?) real-time
applications. Even reassociating to a new access point might take a few
seconds (scanning & finding), or there is packet loss if you get out of
the range from the previous ap until your wifi card changes to another
AP.
Regards
Simon
