Thanks Fernando, That's Ok, the node ID is used in the simulator core. But, it is possible assign real IP addresses to the nodes (not X.Y.Z hierarchical format)? I need the IP addresses because my protocol algorithm does some calculations with them. As a matter of fact, it is not so important IP addresses appear on the trace file. I used trace file just to confirm I can assign them.
I have read something about Address class, ns_addr_t struct, etc. But I didn't understand how I use that. Could you help me with it? Or give me any link? []s, Marlos.
