Modify DSR module

[Peter Gregory]

Hello,

I'm doing a research with ns-3 and I need to modify the DSR module in order to allow some nodes to drop packets, simulating a non-collaborating scenario. 

I tried to edit some files and methods in the DSR module, such as the methods Send and SendPacket in the dsr-routing.cc file, without any results.

How could I do such a thing?

Thanks in advance for any help.

Regards.
