[B.A.T.M.A.N.] Broadcasting of GPS-coordinates?

[Rene Bartsch]

Hi,

I'm new to B.A.T.M.A.N, so a "Hello" to all! :)

Does B.A.T.M.A.N support some kind of broadcasting node positions?

The idea is to broadcast TX-Power/RX-Gain and the position of a node
determined by a GPS-device to create maps with network coverage.

Is that possible anyhow?

Regards,

Renne

No, batman-adv and batmand don't support this kind of semantic data exchange. 
But the new daemon alfred is (will be?) flexibible enough to do these kind of 
things together with batman-adv. Maybe you can ask Simon and help him to 
create alfred.

Kind regards,

I'm doing this with my nodes but I have a garmin receiver hooked up to a 
serial port on a routerstation pro, and using a combination of cat, sed, 
awk, bc, and tail to get determine the coordinates and wget to post them 
to another server that handles the mapping. Pretty simple actually.

That's an option, of course.

But centralized servers are a single point of failure. So my idea is
any node broadcasts his GPS position with TX- and RX-Gain. Any node
can e.g. use a transparent HTTP-proxy to provide a map to the LAN
attached. In case of a Google Maps overlay, each node can be displayed
on the map with a coverage radius calculated by TX-/RX-gain. By using
the "navigator.geolocation.getCurrentPosition".tag the map can be
centered to the current position of the HTTP-client. Info-boxes on the
nodes can use the RX-/TX-gain of the mouse-over-node and the
HTTP-client to show the theoretically maximum link speed. That would
improve nomadic use und finding gaps in network coverage. The
geographic positions can also be use to optimize routing and
beam-forming, e.g. calculating vector and distance of the first
fresnel zone of the next node.

Renne

Yep, we have received quite a few requests to transport arbitrary information
(node gps position, host name, neighbor information, client station list, 
the weather forecast, etc ...). Actually we don't want that in batman-adv
to not bloat the kernel code, so we are currently in the process
to implement a userspace daemon to allow broadcasting this kind of data - in
a clever way, that is collect information on one (or a few) designated servers
and request from then.

This software is called A.L.F.R.E.D (Almighty Lightweight Fact Remote Exchange Daemon),
and it's still in the middle of development[1] and will not be usable for productive
use right now. As soon as it is finished, we will move the vis server to it, and it
will be possible to use for custom purposes (like your tx-power/rx-gain/... info).

I'd like to ask for a little bit more patience, we will announce a release as soon
as we consider it usable. :)

Thanks,
	Simon
