void handler ( NodeContainer &nodes,AppHelper &consumerHelper)
   string s_geoName;
   for(int i=1;i<(int)nodes.GetN();i++)
     Ptr<ConstantVelocityMobilityModel> mob = 
     Vector v_value=mob->GetPosition();
     consumerHelper.SetPrefix (s_geoName);
     consumerHelper.Install (nodes.Get (i));


You can use th ns3 Scheduler to call a function that updates prefix 
every i_t (time units)
for(int i_t=0;i_t<STOP_TIME;i_t++)
      Simulator::Schedule(Seconds(i_t), &handler,nodes,consumerHelper);
