[B.A.T.M.A.N.] Location on the network

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 ?
