thanks a lot !!

"Cluster" is a default function in ns2.

"Multicast" is a default function in ns2.

So I guess it should just be a matter of using / writing the right simulation.tcl .

thanks a lot for ur help

i need to ask one question again is that not necessary to add multicast and clustering function in .cc and .h that means no need to write a code on aodv.cc and aodv.h files and i can write the complete code on tcl files?

thanks in advance

thank very much for ur help but how can i compare the performance of the two protocols? that is why the multicast function and clustering can be done on tcl so how i can compare the two protocols in tcl file

thanks in advance

Cluster and multicast are not really protocols. Just ways of setting up / organizing a network.

There is no "multicast" in the shown clustering examples.

But at least one example in a search with all 3000 simulations : test-suite-hier-routing.tcl

I.e. ns-2.35/tcl/test/test-suite-hier-routing.tcl

The search is attached :

[000-All-examples-4]$ grep -n multicast * > multicast-all.txt
test-suite-hier-routing.tcl:20:#  There is a order dependence of hierarchical routing and multicast: 
test-suite-hier-routing.tcl:22:#  if you turn on hier routing BEFORE multicast, the trace result is
test-suite-hier-routing.tcl:23:#  different from you turn on hier routing AFTER multicast. The reason is
test-suite-hier-routing.tcl:24:#  that set-address-format{} checks multicast from ns-address.tcl; if it's
