running time of NS

[mob@cs.rpi.edu]

Hi, List,

I'm trying to find a formula to estimate the running time of ns simulator.
What I have got now is t(n) = C0 + C1*n + C2*n^2 + C3*n^3 + C4*log(n) +
C5*n*logn(n) + C6*n^2*log(n), where n is the number of nodes, t(n) is the
running time. With similar topology and same application, there should be
some formula to estimate the running time. But I always get some negative
coefficient for my formula.

Does anybody has done similar thing as I? Can you help me?

Any comments are appreciated.
