Hi everyone, this topic may sound odd at first but it actually is not. I am using the Wifi80211pHelper and the QosWaveMacHelper and this is related to some unicast packets.
I set up a 2 Node scenario with a third nonexisting node. Then I prepopulate the ArpCaches of those nodes with each others mac. and ips pairs and in addtion to that with a third pair of ip and mac which is not bound to any existing node.
So far so good.
In the first scenario I am using the existing node. The output seems reasonable to me: A packet is enqueued within the mac queue and sent afterwards. But if I am sending packets to the nonexisting node there are neither packets enqueue nor are there any tries to resend the not acknowledged packets.
The question which now bothers me is: "Why are there no resends?" Due to the protocol the mac should try to resend them at least 7 times until he gives up and drops the packet.
Has anyone an idea, what is going on wrong here? Or am i just mistaken and doing something wron again?

Hello D.G.,
I haven't looked in depth into your code, but if a non-existent node won't do the trick why not try setting a node and putting it very very far away from the other two? From a networking aspect the result would be the same wouldn't it?

My bad. This issue is already solved :) I just did it like you suggested it. Nevertheless I am wondering why injecting of a "virtual node" doesn't work. Thank you Rediet.
