Bow-Nan, C receives everything from A and B regardless of whether the message was unicast or broadcast. All OTA transmissions are sent to all NEMs participating in an EMANE deployment.
In this case, the receive power would be less than the receiver sensitivity and the packet would be dropped by the PHY Layer. A's packet will NOT show up in C's MAC statistics. -- Steven Galgano Adjacent Link LLC On 04/11/2013 11:10 PM, Cheng, Bow-Nan - 0665 - MITLL wrote: > I guess as a related question, could you explain a little how the > broadcast NEM works? > > For example, if I have 3 nodes, A, B, C where due to range, A can talk to > B and C can talk to A, but not A: > > A ---- B ---- C > > If a packet gets sent from A to the broadcast NEM, does C also receive a > copy of this packet?
