Hello, I'm going to compute packet loss for wireless nodes. As you know in trace file "-d" indicates a dropped packet but when node_(0) sends a packet to node_(1) and the receiver node drops the packet, in trace file in related line we can see "-d -t .. Hs 0 ..". How can I change and make the .cc file that generate .tr file so that in trace file it shows "-d -t .. Hs 1 ..", means the node_(1) dropped the packet?
