for emulation (experiments) a good starting point is the RFC 2398 "TCP tools
for implementators"
I especially recommend the combinaison of tcpdump/tcptarce/xplot to analyse
TCP behavior.
I never try to use delay generators mentionned in this RFC, so I don't know
if they are capable to generate changing delay.
For NS, I know there is a TCP stack and some satellite tools. But I never
play with them.
Cheers
