The freshness attribute of Producer app is used for this purpose. Please see 
all the attributes here 

It can be used as 
ndn::AppHelper producerHelper("ns3::ndn::Producer");
producerHelper.SetAttribute("Freshness", TimeValue(Seconds(5))); 

It sets the life time of each data packet to 5 seconds.

Also if you want to use it in your own custom app, please see line 83 in the 
example:examples/ndn-custom-apps/custom-app.cpp in this link 
auto data = std::make_shared<ndn::Data>(interest->getName());
Hope it will help you. Thanks

of them has a lifetime.
