[moussaoui yehya]

thank you sir for your reply
actually i have modified the code and implement more than one producer and try to change the forwarding strategy but i get the same metrics, even i delete this instruction
   ndn::StrategyChoiceHelper::Install(nodes, "/", "/localhost/nfd/strategy/best-route");
it run normally but i get the results.
BTW my scenario apply on Wireless sensor network
this is my code .. please have a look of my code:
