Hi ~ ! My code which has worked well in the 4-vs-4 dumbbell network makes an error in the case of 16-vs-16 dumbbell. Maybe it seems a hierarchical routing problem. Could you show me the sample of 16-to-16 dumbbell which has wireless bottleneck or recommend anything?. Thank you in advance.

I didn't notice any useful responses to the initial cry for help. Forgive me if I'm just being redundant. This isn't an ns-2 problem nor is it a tk-versioning problem. It's simply that the compiler can't find X11 (or XFree86) files it needs to link tk to the underlying windowing system. I had

Hi, We want to calculate the overhead in NS version 2.29 (with Tcl) in order to compar the routing protocols used in the simulation of an ad'hoc network. So , most of the documents we have read said that this task is done by using one of the fields of the trace file , but we didn't find
