Ramon, I think arguments could be made for either ns-2 or ns-3, in the case of SCTP. The group at the University of Delaware put a lot of effort into developing the ns-2 model, over the course of several years, so if the emphasis is really on studying the finer points of SCTP, perhaps you will find that code useful. For ns-3, there is no code available yet, but it appears that a group may post some code for SCTP in ns-3 shortly; please review this thread: https://groups.google.com/forum/#!topic/ns-3-users/SfJ8cLXoXhA There is also the ns-3 DCE kernel code framework; since SCTP is in the Linux kernel, one might be able to reuse this code (although I'm not sure whether in your use case it would be suitable). I checked with Hajime Tazaki about whether SCTP was supported yet for Linux kernel DCE, and he replied "not yet" and that it would probably be a few weeks of work to support CONFIG_IP_SCTP. In general, all things being somewhat equal, you will probably find more help on the lists when using ns-3, since it is actively maintained. You mentioned needs for a number of other models: Ethernet, Fiber, WiFi, ZigBee, PLC, GPRS. I don't think either ns-2 or ns-3 has all of these. Given all of this, probably it makes sense to try both out (existing ns-2, and ns-3 once the SCTP code becomes available). - Tom
