Hi all I have studied on ad hoc multicat routing,especially ADMR and ODMRP. But I have problem to simulate this, because NS 2 not support this routing mechanism (NS 2 just embeded with DSDV, DSR, TORA, AODV). Must I use the multicast extension like in http://www.monarch.cs.rice.edu/multicast_extensions.html ?. Would you like to tell me what steps must I do? Thanks for your attention
