Hi Nour,

To disable content store, you just need to `ndnHelper.SetContentStore("ns3::ndn::cs::Nocache")' prior to calling `ndnHelper.Install(...)'.   You don't need to create multiple helpers (you can, but there is no real need.  You can simply alternate "SetContentStore"/"Install" with normal and null (nocache) CS.

CS is very powerful component of NDN system, but its absence does not prevent communication.
