[ndnSIM] Events randomization

Hi Alex,

I'm not sure if my doubt concerns properly to NDNSim or to the NS3
simulator, but if you could help me it would be great. I'm working with a
simple topology where 2 publishers and 1 consumer are connected together
through a router. All the nodes have the ndn stack installed. Both
publishers are able to serve all the contents that the consumer asks. For
the forwarding strategy I am using Flooding. Once the consumer asks a
content, both the producers receive an interest and respond with a content
object. Both the content objects get the router at the same time, but,
obviously, just one of them satisfies the pending interest and is forwarded
to the next hop. The problem is that the router always select the content
object that came from the same publisher. Such a predictable behavior do
not sounds good for me and I would like to insert some randomness to this
process. I have already tried to change the "RngRun" parameter but the
results were the same and  now I am stuck with this problem.

I thank you in advance.

Best Regards,

Igor Ribeiro.
