[ndnSIM] Testbed nodes geographical locations in mini-ndn

[Ertugrul DOGRULUK]

Hi Spridon,

The problem is printing the topology with real locations. For example, one node located at USA and the OTHER one located in EU, when I tried to print the topology these nodes ends next to each other, I think, they based on link delays not real distances.

So the questions are: Are X amd Y coordinates effects the results or not? How can I get real coordinates from this file (https://github.com/named-data/mini-ndn/blob/master/topologies/current-testbed.conf ).—The created for angle and radius also does not any make sense because node coordinates are not ok, for example UCLA and MINHO angle and radius.

Hi,

if you can figure out the average delays of the testbed links, you can create a text file that reproduces the topology based on the link delays.

I do not understand if your problem has to do with how things look or it is a concern that can impact the simulation results.

Thanks,

Dear ndnSIM developers,
https://github.com/named-data/mini-ndn/blob/master/topologies/current-testbed.conf

The locations of nodes are not correct when I do —vis. For example, “minho” node is locates next to the “ucla”. I do guess they are based by link delays by radius and angles (even I converted them for x and y, they are almost the same). Is there any way to get real geographical ndn-testbed locations by ndnSIM.
