[ndnSIM] ConsumerZipfMandelbrot alpha value?

[Renato Cavalcante]

Dear Jhon

I also noticed this in some papers.
This class:
http://ndnsim.net/2.4/doxygen/ndn-consumer-zipf-mandelbrot_8cpp_source.html,

has the alpha attribute equal to 0.7 as default:
.AddAttribute ("s", "parameter of power", StringValue ("0.7"))

In this example, I changed alpha for 1.0
ndn::AppHelper consumerHelper("ns3::ndn::ConsumerZipfMandelbrot");
consumerHelper.SetAttribute("s", StringValue("1.0"));

I hope that help in some thing.
