Grid routing using Click

[Saurabh Jain]

Hi!

I have a query regarding the Grid implementation in Click.

Is it possible to manage multiple interfaces using Click and Grid? I wish
to create a multihop adhoc network (MANET) where each node has multiple 
802.11b cards. Often I would receive a packet from one link, and
depending on which region it has to go to, send it through another link.
Is it possible to use Click to perform such routing, using the Grid
protocol? Would Click be very resource hungry for such routing, or can I 
use the node like a desktop computer with Click running?

Thanks

Saurabh

Subject: Grid routing using Click

Hello!

I am working on the application of community wireless networks in rural
areas. This is similar to the Rooftop setup which Benjamin A. Chambers
discusses in his Master's Thesis. I find your work to be very exciting
since you are probably the only group to have tried out ad-hoc routing for
community networks in an open-source manner.

In my configuration, there would be only one node per village, hence the
density would be very sparse. For the routing to work well, geographical
forwarding ought to be used, since nodes are fixed and location
information is easily available.

In his report, Benjamin says that the implementation of Grid in Click 
which he used, did not really implement the geo part. Have things changed 
since then?

The Click router page mentions that an IP router was created to test
click's throughput. This means Click should have support for multiple
interfaces. Is it possible to modify Click so that every node with a
user-space, laptop-like Click configuration (as mentioned on your website)  
can use multiple interfaces for routing? That is, I get a packet from one
interface, and depending on its next hop (determined by Grid), I send it
down another interface. Would such a configuration create a heavy load on
the node?

I would like to congratulate all of you on your excellent work. I've been 
working in this field for a long time, but only recently chanced upon the 
Roofnet paper while I was looking for information on GRID. I find Ben's 
work really useful, and so would many other. Maybe you should suggest your 
site/link to Google etc so others could find your work too.

Hope you'll reply soon to my queries.

Thanks

Saurabh
