I'm wondering if its theoretically possible to locate a device physically on the
network. The nodes may have some notion of distance between eachother and therefore time,
and therefore can compute the fastest route. However can any information be gleaned or
added that indicates which direction a node is in relation to north south east or west on
a map?
My challenge is to connect a local group of cellphones to a mesh but to also be able to
define which phones are to the east of a central point which to the west, north and
south.
At this point I'm not even sure if its possible.
Cheers ?

Hi Brani
Are the cellphones using BATMAN, or are they just STA of an access
point co-located with a mesh node? And is your mesh static, or can the
mesh itself move around?
I'm assuming your mesh nodes are static. Thus you can determine there
location once, using GPS, etc, and assume they are not going to move.
If the cellphones are STA, you can tell from the tables that BATMAN
keeps which mesh node they are behind. Thus if you know the location
of the BATMAN mesh node, your know the approximate location of the
cellphone.

In the current implementation of batman-adv a node does not have any idea about its
location and about the direction the message is taking.
This should be somehow handled outside of the module. For example, using the
cellphone, you could get the location using the GPS and then exchange this
information (by means of Alfred?).

So what you need has to be implemented outside, batman-adv cannot help with
that.
