Re: [ns] how to calculate the overhead ?

This is total number of packets transmitted during your simulation, but note that for the packets that have transmitted over multiple hops, each packet transmission on a single hop is count as one transmission, this represents the overhead of your routing protocol. from the trace you can find the
